Description
About the Dress: Portia and Scarlett PS27403C
Portia and Scarlett PS27403C is a long, fully sequined fitted gown that covers every inch from the neckline down to the sweep train in rectangular mirror-like metallic tiles. The tiles are arranged in horizontal rows across the entire dress — bodice and skirt — creating a high-impact, disco-ball finish that catches light from every angle. This is a statement gown built for an entrance.
Fit & Silhouette
PS27403C is cut to follow the body closely from the shoulders all the way through the hips. It does not have a structured skirt or added volume — the fit is slim and body-conscious throughout. At the hem, the silhouette flares slightly into a sweep train, adding just enough movement. A high front slit opens at the thigh, giving the legs room and adding to the dramatic shape. Thin spaghetti straps sit at the shoulders and hold the deep v-neckline in place.
Fabric & Detail
The base of Portia and Scarlett PS27403C is jersey — a smooth, stretch-friendly fabric that allows the gown to conform to the body without stiffness. The entire outer surface is covered in close-set rectangular sequin tiles with a mirror finish, giving the dress its metallic, fully-beaded look. The coverage runs from the top of the bodice to the hem of the train without any break in embellishment. The back is completely open, framed by the crossing spaghetti straps, and the gown closes with a concealed back zip beneath the open-back design.
Key Features
- Fully sequined from neckline to hem — rectangular mirror-tile finish
- Deep v-neckline with thin spaghetti straps
- Completely open back
- High front slit
- Fitted through the body with a slight flare and sweep train
- Jersey base for stretch and comfort
- Available in Silver and Gold
Style & Occasion
Portia and Scarlett PS27403C is built for high-intensity formal events where the dress needs to carry the look on its own. The Silver colorway reads cool and icy under bright lights; the Gold colorway is warmer and richer, leaning toward amber and champagne tones depending on the lighting. Neither color needs much accessorizing — a minimal strappy heel and small clutch are enough. This gown suits prom, formal dance events, pageant competitions, and evening galas. Style it simply: let the sequin surface do the work, keep jewelry minimal, and choose a heel that gives the slit room to move.
Each mirror-sequin panel is stitched to a stretch base, so the gown moves and photographs like liquid metal without stiffness. Keep steam and direct heat away from the sequins; a cool hang after wear is all it needs.

Frequently Asked Questions
Yes, Portia and Scarlett PS27403C can be returned or exchanged if it does not work for you. Here is how the process works at Marlas Fashions so you know exactly what to expect before you order.
Marlas Fashions accepts returns in exchange for store credit, a direct exchange for a different size or style, or a refund minus a 30% restocking fee. The store credit never expires, which means you can use it toward any future purchase without a deadline. If you know you want a different size of the same gown, an exchange is straightforward and avoids the restocking fee entirely.
To qualify for a return or exchange, the gown must come back in its original unworn condition — tags attached, no signs of wear, no alterations made. Trying it on at home over bare skin or light undergarments is completely fine and does not affect the return eligibility, as long as the dress is not damaged or worn further. This is the expected use of a try-on at home.
A few things to be aware of with this specific gown. The sequin tile surface is delicate — rectangular mirror tiles can catch on jewelry, rough surfaces, or fingernails during handling. Try it on carefully, on a clean floor or carpet, and avoid pulling the fabric while getting in and out of it. The high front slit and open back mean fit and comfort are easier to assess on the body than by measurements alone, which makes trying it on at home especially worthwhile.
For a gown at this price point, it is worth checking whether your measurements land between sizes before ordering. If you are right between two sizes, ordering up is usually the better call for a fitted gown like this one — it is easier to take in than to let out, and the jersey base does respond well to minor alterations.
Shipping runs 7 to 12 business days from order, with rush options available. If you have questions about which size to order first or whether a particular colorway is in stock in your size, reach out before placing the order — the team can help you make the right call and reduce the chance of a return altogether.
For any return or exchange questions, contact the Marlas Fashions concierge team: text +1 416-536-2956 or WhatsApp +1 213-868-3131.
Portia and Scarlett PS27403C is designed for high-formality events where a fully embellished, show-stopping gown is the expected dress code — or at least well within range. Here is a straightforward breakdown of where it works and where it is likely too much.
This gown is a strong fit for prom. The fully sequined surface, open back, high slit, and fitted silhouette are exactly what prom styling calls for, and the Silver and Gold colorways both photograph extremely well under venue lighting. If your prom has a formal or black-tie dress code, this gown meets that level without question.
Formal dances and gala-style events are also a natural fit. The sweep train and fully-beaded surface give it enough structure and presence for ballroom or banquet-hall settings. It holds up well on a stage or in front of a crowd.
Pageant competitions are another strong match. The gown qualifies under the over-the-top embellished pageant styling standard — full sequin coverage from bodice to hem, dramatic silhouette, and stage-ready presence. If your competition requires a gown round, PS27403C was essentially made for it.
Evening events at upscale venues — award ceremonies, charity galas, formal birthday dinners — are realistic occasions for this gown if the dress code supports it.
As a wedding-guest dress, the deep plunge neckline, open back, and high front slit suit evening and black-tie receptions best, where a more dramatic look is welcome. The deep plunge neckline, completely open back, and high front slit together make it too revealing for most wedding settings. Wearing it as a guest would likely upstage the wedding party, and at more conservative ceremonies it would simply be the wrong choice. It is also not a fit for semi-formal events, school banquets with a relaxed dress code, or any occasion where a lower-key look is expected.
In short: if the event calls for a fully sequined, body-forward gown and you want to make an entrance, PS27403C is the right dress. If the event calls for anything understated, it is the wrong one.
Both Silver and Gold are available. Silver reads more dramatic under bright venue lights; Gold is warmer and slightly softer in tone. Either works for prom or pageant — the choice comes down to personal preference and what the rest of your look is built around.
Portia and Scarlett PS27403C has an open back by design — the back is almost entirely exposed, framed by the crossing spaghetti straps that run from the shoulders down to the lower back. The actual closure is a concealed back zip that sits at the center back, partially hidden beneath the open design.
Because the gown is fitted in jersey with sequin tile coverage, there is a moderate amount of stretch in the base fabric. The zip holds the fit at the back, but the jersey allows the gown to conform to the body rather than requiring a rigid fit. This means small variations in back width are usually absorbed by the stretch — you are not locked into a single measurement the way you would be in a structured satin or brocade gown.
The spaghetti straps are not adjustable on the standard version of this gown. They are set at a fixed length, which means the fit through the shoulder and bust is determined primarily by the size you order rather than strap adjustment. If the straps feel slightly loose or tight at the shoulders, a tailor can shorten or reposition them — this is a minor alteration that most bridal and formalwear tailors handle routinely.
For the best back fit, pay attention to both your bust measurement and your hip measurement when selecting a size.
Portia and Scarlett PS27403C works in both scenarios, but it reads differently depending on how you use it.
As a solo piece, it is a standout. The fully sequined surface and open back make it visually distinct from almost any other gown in a room, which is exactly why it suits prom queens, pageant contestants, and anyone who wants to be the focal point of the event. If you are wearing it while the rest of the group is in a different style, the contrast works in your favor.
For a coordinated group or court, the key is to commit to the metallic theme across the group rather than trying to match identically. A group where everyone is in sequin or metallic gowns — different styles, same finish family — looks intentional and cohesive. Silver and Gold both sit in that metallic register, so mixing the two colorways within a group reads as a deliberate choice rather than a mismatch.
If you are outfitting a damas or bridesmaid-style court alongside PS27403C, a simpler gown in the same color family tends to work better than matching the same style exactly. The PS27403C is high-intensity; supporting gowns in a sleeker or less embellished cut complement it without competing.
Portia and Scarlett PS27403C is a fitted gown, which means the sizing is more precise than a flowy or A-line style. It does not have extra room built into the skirt, and the fitted silhouette means every inch of the gown needs to work with your body.
Generally, PS27403C runs true to Portia and Scarlett's standard sizing. To find your size, measure your bust, natural waist, and hips, and compare them directly to the brand's size chart. Do not go by your usual clothing size — formal gown sizing and everyday sizing do not correspond reliably.
A few things to keep in mind for this specific gown. The jersey base has some stretch, which helps with fit, but the sequin tile surface has very little give. This means the fit is primarily set by the size you order, not by the fabric stretching to accommodate. If your measurements fall between two sizes, order the larger one. A gown that is slightly too big can be taken in by a tailor; a gown that is too small cannot be let out once the sequin coverage is cut.
For the high slit, the opening sits at the front thigh. The height of the slit relative to your body will vary by height — if you are petite, it may fall higher than expected; if you are tall, it may sit lower. This is easily adjusted during hemming if needed.
The combination of a deep v-neckline, a completely open back, and thin spaghetti straps makes traditional bra styles incompatible with PS27403C. Any bra with a back band or adjustable straps will be visible, and most adhesive bras that cover the full cup will show at the front neckline.
The most common solution for this type of gown is a low-profile adhesive bra or silicone nipple covers. These provide minimal support but solve the visibility problem. For customers who need more lift or support, a low-back bra converter kit can sometimes work — these use a clear strap that attaches below the open section — but the fully open back on PS27403C leaves very little room for attachment points, so test any option carefully before the event.
The jersey base of the gown does have a small amount of built-in structure at the bust from the lining, but this gown is not designed with boning or cups built into the bodice. It is a sleek, minimally structured garment.
For the lower body, seamless underwear or a thong in a color that matches your skin tone is the standard approach under a fitted sequin gown. Any underwear line will be visible through the fitted jersey, so the smoother the undergarment, the cleaner the silhouette.
Height affects this gown in two meaningful ways: the length of the train at the hem and the placement of the front slit.
Portia and Scarlett PS27403C is designed for a standard height of approximately 5'7" to 5'9" without heels. The sweep train at the back hem is designed to graze the floor at that height range. If you are shorter, the train will pool more on the floor, which is a tripping hazard and a practical problem for dancing. If you are taller, the train may not sweep as dramatically and the back hem may rise slightly above the floor.
For the front slit, height changes where the opening falls on the leg. On a shorter frame, the slit will appear to open higher on the thigh. On a taller frame, it sits lower proportionally. Neither is a structural problem — it is a styling difference — but it is worth knowing before you try the gown on.
Hemming a fully sequined gown is a specialty alteration. Standard seamstresses who work primarily in casual or everyday clothing may not have experience with sequin tile surfaces. Look for a tailor who has specific experience with heavily embellished formal gowns. A good alterations tailor will trim the hem from the inside to preserve the tile pattern at the edge, rather than cutting through the tile layout from the outside.
Silver and Gold are both high-reflectivity finishes on PS27403C, and both photograph differently depending on the lighting — which is worth knowing before you decide.
Silver under camera flash or stage lighting tends to read as very bright and icy — almost white in some photos. Under softer or warmer ambient light, like venue chandeliers or candlelight, it reads as a cool, medium silver with more depth and texture visible in the tile pattern. If your event lighting is bright and direct, Silver will be very high-contrast in photos. If the lighting is warm and diffused, it will look more like a traditional metallic silver gown.
Gold behaves similarly but in the warm register. Under bright lighting, it reads as a saturated metallic gold — rich and bold. Under warm ambient light, it shifts toward an amber or champagne tone. Gold photographs well in most lighting conditions and tends to read as slightly more approachable in person than the full intensity of the Silver.
For skin tone, Gold tends to complement warmer undertones and deeper skin tones particularly well. Silver works broadly but can feel stark against very fair skin in direct lighting — though many customers prefer exactly that high-contrast look for prom.
For prom specifically, think about the color of your date's attire and the rest of your group if coordination matters to you. Both Silver and Gold are available through Marlas Fashions.
