Description
About the Dress: Portia and Scarlett XO362
The Portia and Scarlett XO362 is a long fitted gown built on a mesh base that is completely covered in sequins, beading, and floral appliqués from the neckline all the way to the hem. The strapless scoop-neck top sits straight across the chest with a clean edge. What makes this style stand out is the pair of large detachable puff sleeves — wear them on for a dramatic, editorial entrance or remove them for a sleek sleeveless silhouette.
Fit & Silhouette
The Portia and Scarlett XO362 is cut as a true fitted gown — it follows the body through the bust, waist, and hips all the way to the hem. There is no flare below the knee. A front high slit adds ease of movement and shows off footwear without changing the fitted line. This is a sleek, body-conscious silhouette that reads formal and polished from every angle.
Fabric & Detail
The base of the XO362 is a mesh or net ground that is completely covered with sequins and beads. Three-dimensional floral appliqués are distributed across the entire surface — they are especially visible in close-up on the bodice and skirt. Coverage is top to bottom, so this qualifies as a fully-beaded gown with no plain panels anywhere on the dress. The back is fully open, with the entire back exposed from the shoulders down past the waist, meeting the open-back standard.
Key Features
- Fully-beaded mesh gown — sequins, beading, and floral appliqués from top to hem
- Strapless scoop-neck with a clean straight edge
- Detachable dramatic puff sleeves — two completely different looks in one gown
- Front high slit for freedom of movement
- Fully open back for a bold, dramatic back view
- Long fitted silhouette — body-hugging through bust, waist, and hips
- Available in Ivory and Pink
Style & Occasion
The Portia and Scarlett XO362 is built for prom — the fully-beaded surface, dramatic detachable sleeves, open back, and fitted length deliver exactly the kind of statement that prom calls for. It works equally well for pageant competition, a formal gala, or an evening event where a heavily embellished gown is appropriate. The detachable sleeves make it versatile: wear the sleeves for the entrance and ceremony photos, then remove them for dinner and dancing. As a wedding guest, this gown suits evening receptions and black-tie celebrations best, where its open back and sleek silhouette feel right at home. The Ivory colorway reads luminous and bridal-adjacent under event lighting, while the Pink is bold and vivid in photos. Both colors photograph beautifully with the sequin surface picking up venue and stage lighting. Pair with strappy heeled sandals, minimal jewelry, and a small clutch — the dress is the statement and accessories should stay simple. Portia and Scarlett XO362 ships from our Los Angeles and New York warehouses with a standard lead time of seven to twelve business days; rush shipping is available on request.

Frequently Asked Questions
Returns, exchanges, and trying a gown on at home are all reasonable things to think about before spending serious money on a formal dress — here is exactly how it works at Marlas Fashions.
When your Portia and Scarlett XO362 arrives, try it on right away, ideally before removing any tags or steaming the gown. If the fit or color is not right, you have three options: a full exchange for a different size or colorway, a store credit that never expires and can be used on any future order, or a refund minus a thirty percent restocking fee. That restocking fee exists because formal gowns are specialty items that require re-inspection and re-packaging before they can go back into inventory — it is a real cost, and we want you to understand it upfront rather than be surprised.
The single most important thing you can do to protect your ability to return is to try the dress on a clean floor with bare feet or clean socks, keep all the original tags attached, and do not steam or alter the gown until you are certain you are keeping it. Once a gown has been steamed, hemmed, or altered in any way it cannot be returned, so hold off on any tailoring until the fit is confirmed.
For the XO362 specifically, the fully open back and fitted silhouette mean that how the dress sits on your torso matters a lot. Try it on and check that the strapless top sits comfortably at your natural bust line without gaping, that the high slit falls where you expect it to on your leg, and that the fitted length allows you to walk comfortably in your planned heels. If anything feels off, contact us before making any changes to the gown.
Our team is available to help you decide — text us at +1 416-536-2956 or WhatsApp +1 213-868-3131 and we will walk through sizing, colorways, and fit questions with you personally. We would rather help you get it right the first time than process a return.
There are a lot of fitted sequin gowns available at prom season, so it is worth being specific about what sets the XO362 apart.
The most distinctive feature is the detachable sleeves. Most fitted sequin gowns are strictly strapless or have thin fixed straps. The XO362 includes large, dramatic puff sleeves that attach and remove cleanly — you genuinely get two different looks out of one gown. With the sleeves on it reads editorial and fashion-forward, almost runway-level dramatic. With them off it is a classic sleek strapless fitted gown. That versatility is unusual at this price point.
The second thing that stands out is the embellishment coverage. This is not a gown with a beaded bodice over a plain skirt, or sequin panels separated by mesh sections. The sequins, beading, and floral appliqués cover the entire surface of the gown — top to bottom — so it catches light from every angle at every height. The three-dimensional floral appliqués add texture that flat sequin gowns do not have, and that texture reads especially well in photos.
The third differentiator is the fully open back. The entire back is bare from the shoulders down past the waistline. Combined with the high front slit, this gown has a lot of skin visible — it is intentionally bold. If you are comparing it to gowns that have a corset back or a partially covered back, the XO362 is a different category of statement.
Finally, the two available colorways — Ivory and Pink — are both strong choices. Ivory is warm and luminous under stage and event lighting. Pink is vivid and photographs with high contrast against most event backdrops. Neither color looks muted or washed out because the sequin surface amplifies the color rather than absorbing it.
If the drama of the detachable sleeves and open back is what you are looking for, the XO362 is a difficult gown to match on those specific features.
The Portia and Scarlett XO362 has a fully open back — the entire back is bare from the shoulders down past the waistline. That means there is no corset lacing, no zipper running down the back, and no hook-and-eye closure visible on the back panel itself. The closure mechanism is internal or located at a side seam; the back view is intentionally clean and fully exposed as a design feature.
Because the back is open and the gown is fitted through the torso, the fit at the bust and waist is largely determined by the size you order rather than by an adjustable closure. This is different from a gown with a lace-up corset back, where you can take in or let out a couple of inches. For the XO362, sizing accurately from the start is important. Order based on your largest measurement — typically the bust or hips — and plan for any minor adjustments to be made by a tailor at the bust or side seams.
If you are between sizes, the general guidance for fitted gowns is to size up and have a tailor take it in, since removing fabric is straightforward while adding fabric is not possible. The structured bodice holds its shape once fitted correctly.
If you have questions about which size to order for your specific measurements, our team is happy to look at your numbers with you directly before you place your order.
The XO362 works well as a statement piece within a group, but it is not the right choice as a uniform for an entire court or damas group. It is a high-drama, fully-beaded fitted gown with an open back and detachable sleeves — the kind of dress that reads as the lead or feature gown in a group, not as a coordinating style.
If you are the prom queen candidate, pageant competitor, or lead person in a party, the XO362 stands out clearly from simpler or less embellished gowns worn by the group around you. In Ivory it reads distinctly different from white or champagne beige, and in Pink it pops strongly against most other gown colors.
For coordination, damas or court members would typically wear a simpler fitted or A-line gown in a complementary color — something that shares the dressed-up level without competing with the embellishment and drama of the XO362. A group where everyone is in a fully-beaded open-back fitted gown can work visually if the styling is intentional, but the XO362 is specifically designed to stand out rather than blend in.
If you want to discuss colorway coordination for a group order, contact our team — we can often help with availability across multiple sizes and colors.
The Portia and Scarlett XO362 is a fitted gown that follows the body closely through the bust, waist, and hips. It runs close to standard sizing but fitted gowns in general leave very little ease, so it is important to measure carefully.
Measure your bust, natural waist, and hips, then compare all three to the Portia and Scarlett size chart. Order based on your largest measurement. If your bust falls in a size 6 but your hips fall in a size 8, order the 8 and plan for a small adjustment at the bust. Taking in a fitted bodice is a straightforward alteration; there is no extra fabric to let out.
The strapless top requires that the bodice fits snugly enough to stay up without support from straps. If the top gaps or slides, the gown is too large at the bust. If you are between sizes at the bust, sizing down slightly at the chest — if your hips allow — will give you better hold without straps.
Height affects where the high slit falls on your leg and where the hem hits the floor. If you are shorter than average, plan for hemming. If you are taller, check whether the gown length is sufficient in the back given the open-back silhouette.
If you want to go through your measurements with someone on our team, reach out before ordering and we will help you find the right size.
The XO362 is built for events where a high-drama, fully-embellished gown is expected and appropriate. Prom is the primary fit — the heavily beaded surface, detachable sleeves, open back, and fitted silhouette are exactly what makes a prom dress a prom dress. It also qualifies for pageant competition under the fully-embellished long gown standard.
Beyond prom and pageant, the XO362 works for formal galas, evening events, and formal occasions where black-tie or formal dress codes apply. The sequin and bead coverage means it photographs exceptionally well under event lighting and stage lighting.
As a wedding guest, this gown suits evening receptions and black-tie celebrations best, where its open back, strapless top, and sleek fitted silhouette are right at home. It is also not suitable for military ball events, which require a covered back. The heavy embellishment rules it out for events where simpler attire is expected.
The two colorways extend the event range slightly: Ivory is striking under formal event lighting and works for any of the appropriate events above; Pink is vivid and high-impact in photos, ideal for prom and pageant where bold color reads well on stage and in formal portraits.
The XO362 is a strapless gown, and fitted strapless gowns generally include some built-in structure at the bodice. Look for interior boning or a built-in shelf or cup structure along the bust line — this gives the strapless top something to grip against the body. When the bodice is correctly sized at the bust, a fitted strapless gown with internal structure typically holds without additional undergarments for most customers.
Because the back is fully open, a standard bra is not an option. A strapless adhesive bra or fashion tape along the interior bust edge are the most practical choices if you want additional hold or coverage. Stick-on cups are another option if you prefer a lighter feel.
For the lower body, the fitted silhouette means that underwear lines will be visible through the sequin and mesh surface. A seamless thong or no underwear are the standard choices for fitted fully-beaded gowns.
If you are unsure about the amount of built-in support at your specific size, our team can check the construction details with us before you order — measurements and cup size are both factors in how a strapless bodice performs.
Yes, the XO362 can be altered and hemmed, but a fully-beaded mesh gown requires a tailor with experience in embellished formal wear — do not take it to a general alterations shop that primarily handles casual clothing or business wear.
The most common alteration needed on the XO362 is length. If you are shorter than average, the hem will need to be taken up. On a fully-beaded gown, hemming requires removing beads or sequins along the hem line before cutting, then re-finishing the edge. This is a skilled and time-consuming job, and it adds cost compared to hemming a plain fabric gown. Budget at least two to three weeks for this alteration and ask the tailor to show you a sample of how they finish beaded hems before committing.
Bodice adjustments — taking in the side seams or adjusting the strapless top — are straightforward on a fitted gown and do not typically disturb the embellishment on the front or back surfaces. Taking in the waist or hips at the side seams is also achievable.
Letting out is generally not possible on a fitted gown since there is no significant seam allowance built in for expansion. This is why sizing up and taking in is always the better approach than sizing down and hoping to let out.
Do not steam or alter the gown before confirming the fit — once altered it cannot be returned.
