Frequently Asked Questions

How does the back of the Portia and Scarlett PS27104 close and adjust — and what is that bow detail exactly?

The back of PS27104 is one of its defining features, so it is worth explaining clearly. The full back of the dress is open — bare from the shoulder blades down to just above the skirt flare. There is no zipper running up the center back in the traditional sense; the closure is integrated into the open-back construction. At the small of the back, a large satin bow sits where the open back meets the top of the mermaid skirt. This bow is a structural part of the dress — it is how the back panels come together at that point — not a decorative tie-on that can be removed. It is made from the same high-lustre stretch satin as the gown itself and sits flat against the lower back rather than projecting outward like a large ballgown bow. Because the back is open, there is no corset lacing or hook-and-eye column to adjust the fit through the torso. The fit comes entirely from the stretch satin fabric and the cut of the mermaid silhouette itself. This is a key reason accurate measurements matter for this dress: the fabric does have stretch, but the gown is constructed to fit a specific body range at each size. If you are between sizes, size up — it is significantly easier to take in a seam at the side or back than to let out a mermaid gown that is too small through the hips. For the open back to sit correctly, your bra cannot show — the exposure runs high enough that a standard bra is not an option. A low-back bra converter, adhesive bra cups, or built-in support through the bodice lining are the practical choices here. The bodice of PS27104 does have light internal structure at the bust to provide some hold without a bra, but if you need more support, adhesive cups are the most reliable option for keeping everything secure through a full evening of dancing. If you want to confirm exactly how the closure works on the specific size or colorway you are ordering, or if you have questions about how the bow will sit on your frame, reach out before you order — it is much easier to get clarity upfront than to deal with fit surprises at the fitting. Our team can walk you through what to expect based on your measurements.

Which events and occasions is the Portia and Scarlett PS27104 actually right for — and are there events it does not suit?

PS27104 is built for high-formality events where a floor-length, fully rhinestone-covered gown with a dramatic open back fits the dress code. Here is how it lines up against the most common occasions customers ask about. Prom is the primary fit. The mermaid silhouette, all-over hot-stone coverage, and sweep train all read as prom-ready in the best sense — this is the kind of gown that photographs sharply under venue lighting and commands attention on arrival. Both the Black and Rose colorways work well for prom depending on your theme and personal preference. Formal galas and evening events are a strong secondary fit. If you are attending a black-tie or formal gala — a charity dinner, awards evening, or high-formality corporate event — PS27104 has the length and embellishment level to belong in that room. Pageant competitions are a natural setting for this gown. The full-length rhinestone scatter, the mermaid flare, and the dramatic open back with the satin bow are exactly the kind of stage-ready details that read well from a distance under pageant lighting. For wedding guest occasions, this dress works best at evening or black-tie receptions where floor-length formal gowns are welcome. The fully open back and body-conscious mermaid cut make this gown best suited to evening receptions and black-tie wedding celebrations, where a more dramatic silhouette is warmly welcomed by guests. Similarly, if you are looking for a mother-of-the-bride option, this is not that dress — the styling is aimed at a much younger, bolder aesthetic. Military balls are not a fit either. Military ball dress codes typically favor more covered, conservative gowns — the open back alone disqualifies PS27104 for that setting. If you are genuinely deciding between this and a more covered formal gown for a specific event, our team can help you think through the dress code and what will photograph best for your venue. Give us the event details and we can steer you in the right direction — no obligation.

How does the Portia and Scarlett PS27104 fit — should I size up, size down, or go true to size?

PS27104 runs in standard Portia and Scarlett sizing. The mermaid cut — fitted through the bust, waist, and hips before flaring below the knee — means fit is less forgiving than an a-line or ballgown. Measure your bust, natural waist, and fullest hip, then compare all three against the size chart. Order by whichever measurement puts you in the larger size. In a mermaid gown, the hips are almost always the deciding measurement, and stretch satin has a limited amount of give before the seams pull. If you are between sizes, size up. Taking a seam in at the waist or side is a straightforward alteration. Letting a mermaid gown out through the hip — especially one with ruching in the stomach area — is significantly harder and sometimes not possible depending on seam allowances. The ruching at the stomach and hip area does help smooth the fit and is forgiving of minor fluctuations, but it is not a substitute for correct sizing. Plan your measurements carefully and order by your actual numbers, not by what you wear in everyday clothes. Formal gown sizing runs differently from street clothing. If your measurements split across two sizes or you have specific fit concerns about a mermaid silhouette, contact us before ordering. Our team can review your numbers and help you decide. We would rather spend five minutes on a call than have you receive a gown that does not fit the way you expected.

What undergarments work under the Portia and Scarlett PS27104 with its open back?

The open back of PS27104 runs high — fabric covers the shoulders at the strapless neckline edge, but the back is bare from there down to the small of the back. A standard bra is not an option. Your three practical choices are: adhesive bra cups (the most popular for this style), a low-back bra converter attached to a regular bra and worn very low, or relying on the built-in bust lining of the gown itself. PS27104 has light internal structure at the bust — boning or a shelf layer depending on your size — which provides a baseline of hold without a bra. For most cup sizes up to a full C, the internal support is enough for a formal evening. If you are a D cup or above and know from experience that you need more support for dancing and moving, adhesive cups are the reliable choice. Look for silicone adhesive cups with a front clasp, sized to your cup. For the bottom half, seamless underwear or a low-cut thong works best under the stretch satin — the fabric is smooth enough that lines can show. Shapewear is an option if you choose a style that does not extend past the hip line of the dress, since the mermaid flare starts below the knee and you do not want compression shapewear restricting movement in the skirt. If you have specific questions about what works under this particular silhouette, feel free to ask when you contact us.

Can the Portia and Scarlett PS27104 be altered or hemmed, and how should I handle the mermaid train?

Standard alterations — taking in the waist, adjusting the side seams through the bust, or tapering the bodice — are straightforward on this gown and a good tailor can handle them without difficulty. The stretch satin is easy to work with and the ruching at the stomach means a skilled seamstress can adjust that section without disrupting the gathered pattern significantly. Hemming a mermaid gown is the one alteration that requires care. The flare of the skirt is cut on a curve, and the sweep train adds length at the back. If you are petite and the train is too long, a tailor needs to shorten the hem while maintaining the curve and the shape of the flare — this is not a straight-across cut. It is worth a few extra dollars to bring it to someone who has worked on mermaid hemlines before. We recommend taking the dress to a formal-wear alteration specialist rather than a general tailor if this is your primary concern. For the bow detail at the back — it is part of the gown construction. Do not attempt to alter or remove it at home. If it needs any adjustment, that goes to a professional. The beading and hot-stone scatter around the back area should also be handled carefully during any alteration work — a seamstress who works regularly with embellished gowns will know how to protect the stones during fitting and pinning.

How does the Black colorway compare to the Rose colorway in person — and how do I choose?

Both colorways are available and photographed. In person, Black reads as a sharp, high-contrast gown — the hot-stone rhinestones pop brightly against the dark base, and under event lighting the effect is very bold. It photographs cleanly and is one of the strongest choices if your prom or event has a darker or more dramatic aesthetic. Black also has the practical advantage of not showing variation across different light sources — it looks the same under tungsten, LED, and flash photography. Rose is warmer and more varied. In person it reads as a medium-to-deep rose pink, warmer than blush but lighter than fuchsia. Under natural light it leans softer; under yellow or warm venue lighting it can pull slightly peachier. Under cool or flash photography it tends to read more purely pink. If your event has a warmer or more romantic palette — think soft uplighting, candlelight, garden venues — Rose can look stunning. If the venue has very cool lighting, verify whether the warmth of the colorway suits the setting. If you are deciding between the two and cannot order a swatch, the most reliable approach is to contact us and describe your venue's lighting and your event's colour palette. We have seen both colorways on customers across a range of events and can give you a straightforward opinion.

How does Marlas Fashions ship the Portia and Scarlett PS27104, and how long will it take to arrive?

Marlas Fashions ships from warehouses in Los Angeles, New York, and — for Canadian customers — Toronto. US and Canadian customers pay no duties. Standard delivery takes 7 to 12 business days from the date your order is confirmed and the gown is allocated. If your event date is close, rush shipping is available — contact us at the time of ordering so we can confirm availability and the fastest realistic ship date for your size and colorway. All shipments are tracked. You will receive tracking information once the order ships. International orders outside the US and Canada ship worldwide with tracking, though duties and import fees may apply depending on your country — confirm with us before ordering if you have questions about your destination. If you need the dress by a specific date, tell us the date when you place the order. We will confirm whether standard or rush shipping gets it there in time, and we will be honest if the timeline does not work so you can make the best decision for your event.

What is Marlas Fashions' return and exchange policy for the Portia and Scarlett PS27104?

Marlas Fashions accepts returns for store credit that never expires, exchanges, or a refund less a 30% restocking fee. The return must be initiated within the return window from delivery — contact us as soon as you receive the gown if there is an issue. Gowns must be returned in their original unworn, unaltered condition with all tags attached. Any sign of wear, alterations, or damage will affect eligibility. If you are ordering this gown specifically for prom or a pageant and are unsure about sizing, we strongly recommend finalizing your measurements before placing the order rather than ordering multiple sizes to return one — the restocking fee makes that approach more expensive than a quick sizing consultation upfront. For questions about a specific order, exchanges for a different size in the same style, or anything about the return process, text or WhatsApp us at +1 416-536-2956 or +1 213-868-3131 and our team will sort it out for you quickly. We have been fitting customers in designer formal wear for over 40 years, and we stand behind every dress we ship.
