Frequently Asked Questions

What is your return policy, and can I try this dress on at home before deciding to keep it?

Yes — you can absolutely try Portia and Scarlett XO309 at home before committing. Marlas Fashions accepts returns on unworn, unaltered dresses with tags still attached. You have three options when you return: a full store credit (it never expires, so you can use it whenever you find the right dress), an even exchange for a different size or color, or a refund minus a 30% restocking fee. The restocking fee exists because each dress is individually inspected and repackaged before it can go back on the floor. That said, the store credit route is genuinely useful — many customers try a dress at home, realize they want a slightly different color or size, and use the credit to reorder the exact swap. To be eligible for any return, the dress must come back in the same condition it was shipped: no wear, no alterations, no stains, no removed tags. We do not accept returns on dresses that have been hemmed, taken in, or otherwise altered, so hold off on booking your tailor until you have confirmed the dress is a keeper. Given that XO309 has a lace-up corset back, you have a built-in sizing buffer — you can try it on, lace it to your measurements, and get a realistic sense of how it will fit at the event before you make a final decision. If you are genuinely torn between two sizes, order the one that fits your hips (the widest point) and use the corset lacing to bring in the waist. Most customers find this eliminates the guesswork entirely. Shipping runs 7–12 business days standard, with rush options available if your date is close. For any questions before or after your order, you are welcome to text or WhatsApp our team — we are happy to walk through sizing, colors, or the return process with you in real time.

What makes Portia and Scarlett XO309 stand out from other fitted long prom gowns?

A lot of fitted long prom gowns choose one focal point — a heavily beaded bodice, a dramatic slit, or a bold back closure. XO309 layers several details that each hold their own without competing. The scattered pearl embellishment is the most visible distinction: pearls are placed across the bodice and run down the skirt, but the spacing keeps the dress from reading as fully covered. The effect is refined rather than maximalist — it photographs well from every angle without overwhelming the wearer. The diagonal ruching is the second detail that separates it. Most ruched gowns run ruching straight across the stomach. XO309 runs the gather diagonally from the bodice across the hip, which creates a more sculptural shape and tends to be more flattering across a wider range of body types. It draws the eye across the body rather than straight across, which reads as more dynamic in photos. The third differentiator is the combination of the front high slit with the sweep train. The slit sits in the front seam panel — it shows when you walk or dance, which creates movement without cutting through the fitted skirt itself. The train is a sweep length, meaning it extends just enough to photograph beautifully without requiring you to carry it. Finally, the lace-up corset back does real structural work here. The boning inside the bodice holds the sweetheart neckline up without any straps, and the lace-up back lets you adjust fit to your body rather than relying entirely on a seam alteration. For a strapless gown worn for a full evening of dancing, that combination of boning and lace-up closure is genuinely more secure than a standard zipper back at the same price point. The result is a gown that works for prom, formal dances, evening galas, and pageant stages — dressed up or pared down depending on how you accessorize.

How does the lace-up corset back work, and how do I adjust it for the right fit?

The back of XO309 closes with a lace-up corset closure that runs the full length of the back seam. To put it on, step in from the top or pull it over your head, position the bodice so the sweetheart sits correctly across the bust, and then have someone lace it up from the bottom, working their way up. You want the lacing firm enough that the bodice does not move when you walk, but not so tight that it restricts breathing or creates visible compression at the back. The standard approach is to lace to your comfort and tie off at the top with a bow that can be tucked away. Because the back has crisscross lacing, you can redistribute tension along the back — tighter at the waist, slightly looser above the hips — which is harder to do with a standard zip. If the dress arrives and the gap between the two back panels is large, that simply means you ordered a size up from your bust measurement, which is common when customers are fitting to their hips first. A tailor can take in the side seams to eliminate the gap if needed, but most customers manage it entirely through the lacing without any alteration. If you are unsure how snug to lace, aim for two fingers of room — you want security without restriction, especially if you plan to eat, sit, and dance for several hours.

Can I coordinate XO309 with a court or damas group, and does it come in enough colors?

XO309 is available in Periwinkle, Pink, and Sage — three distinct colors that are different enough to individualize each person in a group while still reading as coordinated when photographed together. Periwinkle and Sage both photograph as cool tones, so they pair naturally. Pink is the warmest of the three, and it sits well alongside either of the other two without clashing. If your group wants a mixed-color court, a practical approach is to assign one color to the queen or honoree and distribute the other two across the court members. Because the gown silhouette is identical across all three colors, the group reads as unified in photos even when the colors differ. For larger groups, we recommend confirming availability of all three colors before placing individual orders — contact our team and we can check current stock across sizes and colorways so no one ends up with a substitution at the last minute.

Does XO309 run true to size, and how should I measure for the best fit?

XO309 runs true to standard Portia and Scarlett sizing. To find your best size, measure your full bust, natural waist, and the widest point of your hips, then compare to the designer's size chart. For this gown, hip measurement is usually the deciding factor — the fitted skirt has limited ease through the hips, so size to your hip first. If your bust and hip fall in different size ranges, size to the hip and use the lace-up corset back to bring in the waist. Standard prom dresses are cut for a height of approximately 5'9" with heels. If you are shorter, plan for a hem alteration — the sweep train and front slit both affect where the hem needs to land, so work with a tailor who has experience with formal gowns. If you are taller, the sweep train may sit closer to the floor than shown, which can actually look intentional. For personalized sizing guidance, our team is happy to help you measure and compare before you place your order.

What occasions is Portia and Scarlett XO309 suitable for beyond prom?

XO309 is designed primarily for prom but the level of detail and the fitted evening-gown silhouette make it appropriate for a wide range of formal events. Formal dances and school galas are a natural fit. Evening award ceremonies, charity galas, and formal fundraisers work well because the gown reads sophisticated rather than exclusively teenage-prom. Pageant competitions are another strong match — the pearl embellishment, the train, and the structured bodice all translate well on a pageant stage. For black-tie events, the sweep train and pearl detail give it enough formality, though the front slit and the open lace-up back make it more suitable for younger wearers or fashion-forward guests than for conservative formal occasions. As a wedding guest, the open back and front slit suit evening receptions and black-tie celebrations best, where a dressed-up, fashion-forward look is fully at home. Every XO309 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO309, send our team your measurements before ordering and we will advise.

What undergarments work best with a strapless boned sweetheart gown like XO309?

The boned bodice of XO309 is built to support the sweetheart neckline without straps, so most wearers do not need an additional bra. If you want extra security, a strapless adhesive bra or a low-profile sticky bra cut below the sweetheart line works well — just make sure it sits below the neckline so it does not show. Standard underwear works fine since the jersey skirt drapes smoothly, but if you want a completely smooth line through the ruched hip section, seamless briefs or shaping shorts are a clean option. Avoid anything with a visible waistband that sits above the hip, as the diagonal ruching in that area is fitted and will catch the outline. Shapewear that extends below the high slit line can bunch at the opening when you walk, so keep any shaping garments to mid-thigh or shorter. If you are wearing the gown for a long evening, comfort through the waist matters — the corset back lets you adjust the fit as the night goes on, so you are not locked into one level of tightness from the moment you put it on.

How does the color look in person, and which colorway should I choose?

All three colorways — Periwinkle, Pink, and Sage — are photographed in the product images, so you are seeing accurate representations of the actual fabric. Periwinkle is a medium cool blue-purple that reads distinctly under ballroom or event lighting; it is a strong choice if you want a color that stands out without going into jewel-tone territory. Pink is a soft, warm mid-pink that photographs well in natural light and under indoor event lighting — it is the most universally flattering of the three and tends to read a little lighter in person than it appears on screen. Sage is a muted, dusty green that sits in the fashion-forward range; it reads more grey-green in low light and more green in daylight. If you are choosing based on photos, keep in mind that screen calibration can shift perceived color slightly — Sage in particular can appear slightly bluer or greener depending on your device. If you are deciding between two colors and cannot see them in person, our concierge team can sometimes provide additional reference photos or fabric comparisons.
