Description
About the Dress: Portia and Scarlett XO350
The Portia and Scarlett XO350 is a long fitted mermaid gown built around a pearl-covered halter bodice and a nearly fully open back. The high-neck halter neckline frames the collarbone cleanly, while dense 3D pearl dot embellishments cover the entire bodice for texture and presence. Below the waist, the skirt shifts to smooth stretch jersey with subtle ruching at the hip and a sweep train at the hem. The Portia and Scarlett XO350 is available in four colorways: Black with champagne beige, Ivory with champagne beige, Pink, and Blue.
Fit & Silhouette
The XO350 is a true mermaid silhouette — fitted through the bust, waist, and hips, then flaring gently below the knee into a modest sweep train. The stretch-jersey skirt moves with you without losing its shape through the body. The ruching at the waist-to-hip transition adds a small amount of ease and smooths the fit across different hip profiles. This is a form-fitting gown built for a confident, close-to-the-body look from top to hem. If you are between sizes, sizing up is usually the better call on mermaid silhouettes — the fitted hip panel has very little stretch allowance.
Fabric & Detail
The bodice fabric is a sheer base completely covered in small 3D pearl dot embellishments — dense, tactile, and luminous. The skirt is stretch jersey, which drapes cleanly and does not add volume or stiffness. The pearl-to-jersey transition happens at the natural waist, and horizontal gathering at that seam creates a smooth, defined hip line. The sweep train is cut from the same stretch jersey as the skirt — no extra fabric layers, no stiffening. The halter strap is the only back coverage; the rest of the back is open from the neck strap to the base of the spine.
Key Features
- High-neck halter neckline with a dense pearl-dot bodice
- Stretch-jersey mermaid skirt with a sweep train
- Ruching at the waist and hip transition
- Nearly fully open back — only the halter strap crosses the back
- Sleeveless; no additional straps or sleeves
- Available in Black/champagne beige, Ivory/champagne beige, Pink, Blue
Style & Occasion
The Portia and Scarlett XO350 is designed for prom, formal dances, evening events, and galas. The pearl bodice makes a strong statement without heavy beading across the full gown — the skirt stays clean and the silhouette stays sleek. For footwear, a strappy heeled sandal or a simple pointed-toe heel keeps the minimalist feel of the skirt intact. Minimal jewelry works best here: small pearl studs or a simple gold chain let the bodice do the work. Black/champagne beige reads as the most dramatic option; Ivory/champagne beige and Pink are softer; Blue is striking under event lighting. If you are dressing a group, the clean mermaid skirt in different colorways coordinates easily without being overly matched.

Frequently Asked Questions
The XO350 has two different fabric zones, and each one needs a slightly different approach.
The bodice is covered in 3D pearl dot embellishments attached to a sheer base. These pearl details are delicate — pressing or crushing them will flatten or dislodge them over time. For cleaning, spot-treat the bodice with a damp cloth and a small amount of mild detergent. Work gently and avoid rubbing the pearls against each other. Do not machine wash or tumble dry this gown. If the dress needs a full clean after wearing, professional dry cleaning is the safest route. Tell the cleaner about the pearl bodice upfront so they handle it face-up and do not press directly onto the pearls.
The stretch-jersey skirt is more forgiving, but it still should not go in a washing machine unsupervised. Jersey can pill and the mermaid hem can lose its shape if agitated in a machine cycle. Hand wash in cool water with gentle detergent, or dry clean with the bodice.
For storage, hang the gown on a padded hanger to protect the halter strap and bodice weight. Do not fold the dress at the waist — folding over the pearl section will stress the embellishments at the crease. If you need to store it flat, place the gown pearl-side up on a clean surface with tissue paper over the bodice to protect the details from contact pressure. Cover with a breathable garment bag, not plastic.
For travel, the safest method is to lay the gown flat in a hard-sided suitcase or a dedicated garment bag with a fold at the smooth jersey skirt — never at the pearl bodice. Roll tissue paper loosely and tuck it around the bodice to prevent the pearls from pressing against the fabric folds. If you must fold the bodice, place tissue between each layer.
Once you arrive, hang the gown immediately. Any minor jersey creases from transit will usually drop out on their own within a few hours of hanging. For stubborn wrinkles in the skirt, use a handheld steamer on low heat held well away from the fabric — never iron directly on jersey or anywhere near the pearl section.
The XO350 is built around two clear contrasts: a textured, pearl-covered bodice and a smooth, plain jersey skirt. Accessories that match the clean skirt side work better than accessories that compete with the pearl side.
For shoes, a strappy heeled sandal in metallic gold, silver, or a nude-tone is the strongest choice. The open back and halter neckline frame the upper body, so a shoe with some delicacy and height keeps the whole look proportional. Block heels and platform shoes can work if comfort is the priority, but keep the silhouette of the shoe simple — chunky embellishment on the shoe will fight the pearl bodice. Pointed-toe kitten heels or mules also work for a cleaner look on the skirt hem. If you are wearing Black/champagne beige, a gold or warm-toned sandal is a natural complement. For Ivory/champagne beige or Pink, blush or silver both read well. For Blue, silver or cool-toned metallics are the cleanest pairing.
For jewelry, the pearl bodice is the focal point, so the best approach is restraint. Small pearl stud earrings echo the bodice theme without overloading the look. A thin gold or silver chain bracelet, or nothing at all on the wrist, keeps the arm line clean under the halter. Avoid large statement necklaces entirely — the high neck halter neckline does not have space for a necklace, and one would compete with the pearl detail directly below it. If you want earrings with more presence, drop earrings in a single metal finish (no additional stones or pearls) work better than chandeliers.
For a bag, a small clutch in satin, metallic, or plain fabric is ideal. The sweep train means you will likely carry the clutch in hand for most of the event — keep it light. Avoid embellished bags that echo the pearl detail too closely or the look becomes repetitive.
A final note on color: the champagne beige mesh or lining panels in the Black/champagne beige and Ivory/champagne beige versions tone the look without adding color. If you want a bridal-adjacent feel, Ivory/champagne beige is the one to choose. For a bolder, more formal look under event lighting, Black/champagne beige and Blue both read sharply.
The XO350 suits bodies that carry their proportions evenly from waist to hip — the mermaid silhouette is fitted through those areas, and the ruching at the waist-to-hip band helps smooth the transition. The ruching adds a small amount of visual ease at the widest part of the hip without adding fabric bulk, which means the gown flatters curvier hip profiles better than a plain-seam mermaid would.
The high-neck halter neckline creates a long vertical line from the collarbone to the shoulder, which adds perceived height. The pearl bodice draws the eye upward and keeps the focus on the upper body, which balances out a fuller hip or skirt flare below. For anyone who prefers more coverage at the back, it is worth noting clearly: this gown has a fully open back. The halter strap is the only coverage from the neck down the spine. That is part of the design and part of what makes this gown feel sleek — but it is a consideration if back coverage matters to you.
The fitted jersey skirt through the legs is very close-cut, so taller frames tend to move in it more comfortably. Petite wearers can absolutely wear this gown, but high heels are strongly recommended to avoid the hem dragging. Alterations to the hem length are straightforward on a stretch-jersey skirt and do not affect the train significantly.
The Portia and Scarlett XO350 ships from Marlas Fashions' Los Angeles or New York warehouses for US orders, and from our Toronto warehouse for Canadian orders. US and Canada orders have no import duties. International orders ship worldwide with full tracking included.
Standard delivery runs 7 to 12 business days from the time your order is confirmed. If you need the gown sooner, rush shipping options are available at checkout — select the rush option that matches your event date, and the team will confirm availability for your colorway before processing. If you have a firm event date and are cutting it close, reach out before placing your order so the team can check warehouse stock on your size and color directly. Every XO350 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO350, send our team your measurements before ordering and we will advise. Popular colorways of the XO350 sell out quickly each season, so early orders get first pick.
Yes — Marlas Fashions ships the gown to you and you can try it on before deciding. If the fit or color is not right, you have a few options: exchange it for a different size or colorway, return it for store credit (store credit does not expire), or return it for a refund minus a 30% restocking fee.
To keep your return options open, try the gown on carefully before removing any tags and without wearing it to your event. Tags must be intact and the dress must be unworn and unaltered. If you are between sizes or unsure about the mermaid fit through the hips, ordering your most likely size and having a backup plan is a practical approach — the stretch jersey does have some give, but not a lot.
For exchanges on colorways, availability depends on current stock. Reaching out before placing your order to confirm which colors are in stock in your size is always a good idea, especially for prom season when inventory moves quickly.
Most high-neck mermaid gowns at this price point use a solid fabric across the entire bodice — embroidered lace, sequin, or plain crepe. The XO350 uses 3D pearl dot embellishments on a sheer base, which creates a surface texture that reads differently under light than flat embroidery or sequin. The pearls catch light softly and diffusely rather than reflecting it sharply, which gives the gown a more refined look under both daylight and event lighting.
The second defining detail is the contrast between the bodice and skirt. The skirt is completely plain stretch jersey — no embellishment, no texture — so the eye goes immediately to the pearl bodice and the open back. That restraint is deliberate and is what gives this gown a minimalist silhouette despite having a highly embellished top half.
The sweep train is also cut from the same plain jersey as the skirt rather than from a separate fabric or lace overlay, which keeps the hem clean and the overall look cohesive. These details together make the XO350 a gown that reads as sleek and intentional rather than heavily decorated.
The XO350 has a halter neck strap that ties or fastens at the top of the back. From there, the back is open — there is no zipper, no lace-up, and no corset closure running down the spine. The halter strap is the primary fit adjustment point for the bodice. This means the gown is sized through the bust and hip at the time of order, and the halter strap provides a small amount of adjustment at the neckline.
Because there is no back zipper or lace-up system, there is no way to take in or let out the fit from the back after purchase. Fit adjustments to the bodice or skirt need to be done by a tailor at the side seams or waist seam. For this reason, getting your measurements right at the time of ordering — particularly bust and hip — is more important on this gown than on a style with a lace-up or corset back that can be adjusted after delivery.
The XO350 coordinates well in a group setting because the silhouette and design are consistent across all four colorways. If you are the focal point of the group — prom queen, quinceañera honoree, or a solo formal — the Black/champagne beige version reads the most distinct. If the goal is a coordinated court or damas look with variation across the group, the four colorways (Black/champagne beige, Ivory/champagne beige, Pink, Blue) allow each person to wear a different color in the same silhouette.
For a prom party where everyone is in different gowns, the XO350's clean mermaid silhouette and pearl bodice read clearly in group photos without overwhelming other gown styles nearby. The minimalist skirt keeps the look from clashing with more embellished gowns in the same frame.
