Description
About the Dress: Portia and Scarlett XO178
Portia and Scarlett XO178 is a long strapless A-line ballgown with a sweetheart neckline. The bodice is a pearl-beaded corset construction, and the skirt is smooth satin with a high front slit, side pockets, and a sweep train at the hem. The back is fully covered and closes with a zipper. XO178 is available in Periwinkle, Black, Mint, Pink, and Yellow.
Fit & Silhouette
Portia and Scarlett XO178 follows a classic A-line ballgown shape. The corset bodice is boned and structures the waist firmly, holding the strapless sweetheart neckline securely in place without straps. From the waist, the satin skirt flows out in a full A-line sweep to the floor. The silhouette is defined at the top and relaxed from the hip down, which works well across a wide range of body types. The high front slit adds movement without changing the overall line of the gown. Sizes run from 00 through 16.
Fabric & Detail
The bodice of Portia and Scarlett XO178 is covered in pearl beading over a boned corset construction. The pearl embellishment runs across the entire bodice and gives it a soft, luminous texture. The skirt transitions into smooth satin, clean and unembellished, which creates a clear contrast with the detailed bodice. At the hem, the skirt extends into a sweep train. The high slit is cut into the front of the skirt for ease of movement. Two hidden pockets are built into the skirt seams.

Style & Occasion
Portia and Scarlett XO178 is made for prom, sweet 16 celebrations, and debut balls. The pearl-beaded bodice gives it enough detail for a formal ballroom setting, while the clean satin skirt keeps the overall look refined rather than over-the-top. The pockets are a practical detail that gets noticed — no need for a clutch if you don't want one. For styling, strappy heeled sandals work well under the high slit, and minimal jewelry lets the pearl beading on the bodice do the talking. A simple earring or delicate necklace is enough. The gown is photographed in Periwinkle, Black, Mint, Pink, and Yellow — each colorway reads differently in person, so check the individual color swatches carefully before ordering. It is offered in Periwinkle, Black, Mint, Pink and Yellow, in sizes 00 to 16, and every order is checked by hand before it leaves the boutique so the fit and finish arrive exactly as photographed.

Frequently Asked Questions
Yes, and XO178 is well set up for group ordering specifically because it comes in five distinct colors — Periwinkle, Black, Mint, Pink, and Yellow. A court or damas group can coordinate by putting everyone in the same color, mixing two colors like Periwinkle and Mint for a complementary palette, or assigning a standout color to the main person and a secondary color to the rest of the group. The design of the gown is identical across all colorways, so the silhouette and pearl-beaded bodice stay consistent while the colors differentiate roles. That consistency makes for clean, uniform photography. For group orders, the most important thing is to place all the sizes together at the same time rather than in separate orders. Satin dye lots can vary slightly between production runs, and gowns cut from the same run will match more closely than those ordered weeks apart. If your group has a mix of standard and extended sizes, check at the time of order that all the sizes you need are in stock in your chosen color. Lead time matters for group orders. Portia and Scarlett XO178 ships from our Los Angeles or New York warehouse, and standard delivery is 7–12 business days. Rush shipping is available if your event date is tighter. Build in extra time for alterations — the corset bodice and sweep train both require precise fitting, and hemming a ballgown for height takes a full appointment with a tailor. For a group, multiply that time by the number of people and book alteration appointments early. If you're coordinating a large group and want guidance on color combinations, sizing across a range of body types, or logistics for a specific event date, the Marlas team can help. Text or WhatsApp us at the concierge number and we can walk through it with you directly.
Portia and Scarlett XO178 fits true to size for most people, but the construction of the bodice means that getting the chest and waist measurements right matters more than the size number on the tag. The bodice is a boned corset structure, which means it is rigid and does not stretch. If you are between sizes in the chest or waist, sizing up and having the bodice taken in by a tailor is the right move — it is much easier to take in a boned corset than to let it out. The skirt is satin and flows from the waist, so the skirt size is less critical than the bodice size. If your hips and waist fall into different size ranges, fit to your larger measurement and adjust the waist at alterations if needed. To get your measurements right, measure your chest at the fullest point, your natural waist, and your hips at the widest point. Compare those numbers to the Portia and Scarlett size chart — not to your general dress size, which can vary by brand. Sizes run from 00 to 16. For height, the gown is cut for a standard height of around 5'7" to 5'9" in heels. If you are shorter than that, plan for a hem. The sweep train at the bottom means the hem is long and will need to be adjusted if the gown drags significantly. This is a standard alteration, but it takes time, so schedule it as soon as your gown arrives. The boned bodice provides strong structural support and holds the strapless sweetheart neckline in place without needing to be pinned or taped for most people. If you have a smaller bust, a strapless bra or adhesive cups can add extra security, but the boning itself does a lot of the work. If you have any questions about your specific measurements or fit concerns, the Marlas team is available to help you work through sizing before you order.
Portia and Scarlett XO178 is made for prom, sweet 16 celebrations, and debut balls. The pearl-beaded corset bodice and sweep train make it a true formal ballgown, so it fits naturally in settings where a full-length gown is expected or appropriate. For prom, it is a strong choice — the strapless silhouette, pearl detail, and satin skirt hit the right level of formality without being over-embellished. For a sweet-16 or debut, it has the structure and elegance those events call for, while still feeling like a celebration dress rather than a purely formal ceremony gown. The high front slit adds a modern edge to what is otherwise a classic silhouette. The sweep train and ballgown scale make it a full formal-occasion dress. Wear it where the setting matches the gown. Every XO178 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO178, send our team your measurements before ordering and we will advise. Popular colorways of the XO178 sell out quickly each season, so early orders get first pick.
Yes. The bodice of XO178 is fully boned, which means the structure holds the sweetheart neckline in place and supports the chest without needing a traditional bra. For most people with a B to D cup, the boning alone provides enough hold that you can skip a bra entirely. If you prefer extra security — especially for dancing or a long night — a strapless adhesive bra or silicone cups work well and stay hidden completely under the strapless neckline. Avoid regular underwire bras, which will show above the sweetheart line. For the skirt, the satin is smooth and lies cleanly, so a seamless thong or no-show shorts work best to avoid visible lines. The pockets mean you don't need to carry anything that might require a bag to tuck away. If you are going to be standing, dancing, or moving for several hours, the boned corset does a lot of structural work but can feel firm over a long evening. Wearing it for a few hours before the event to break it in slightly is worth doing.
Yes, and it is a common alteration for this style. The gown is cut for a standard heel height of around 5'7"–5'9" in heels. If you are shorter than that, the sweep train will drag on the floor and the hem will need to be taken up. Hemming a ballgown with a satin skirt and a sweep train is a moderate alteration — not complicated, but it requires a skilled tailor and a proper fitting in your shoes. Bring the exact heels you plan to wear to the fitting so the hem is pinned at the right length. The bodice can also be taken in at the waist or sides if you are between sizes. Because the corset is boned and structured, those adjustments should be done by a tailor who has experience with boned bodices — it is not a beginner alteration. The slit height is set into the skirt and is not typically altered, but the overall hem adjustment will naturally bring the slit into the right proportion for your height once the hem is done. Plan alteration appointments as soon as the gown arrives so you have time before your event.
The boned corset bodice is structured and firm, which is what keeps the strapless neckline in place all night. It does feel different from a soft-bodice dress — it holds its shape rather than moving with you, which some people find supportive and others find restrictive after several hours. If you have never worn a boned corset gown before, wearing it at home for a couple of hours before the event helps your body adjust to the structure. The satin skirt is fluid and moves easily. The high front slit means your legs have full freedom of movement, which makes dancing much more comfortable than a closed-hem ballgown. The pockets mean your phone or essentials stay on you without needing to carry anything. The sweep train at the back is worth practicing with — moving backward or sitting down requires being aware of where the train sits. Most people get used to it quickly, but it is worth walking around in the gown before you are in a crowd.
The gown is available in Periwinkle, Black, Mint, Pink, and Yellow. Satin reflects light strongly, which means the colors can look slightly more saturated or luminous on screen than they appear in person under indoor event lighting. Under warm lighting, all five colors will read slightly warmer than in the product photography, which is typically shot under neutral or cool studio light. Periwinkle is a soft blue-purple — in person it tends to look softer and more lavender than it does on screen. Mint is a cool, light green. Pink is a soft warm pink rather than a hot or neon pink. Yellow is a true medium yellow. Black is consistent across lighting conditions. If color accuracy matters — for example, if you are coordinating with a group — look at the gown in the type of lighting your venue uses before committing. If you are unsure between two colors, the Marlas team can answer specific color questions before you order. Text us at +1 416-536-2956 or WhatsApp +1 213-868-3131 and we will help you make the right call.
Satin is a delicate fabric that marks easily and does not recover well from rough handling. After wearing the gown, have it professionally dry cleaned rather than attempting home washing — satin can water-spot and lose its sheen with improper cleaning. For storage, hang the gown in a breathable garment bag rather than a plastic bag, which traps moisture. If the train folds during storage, the satin can crease, so give the gown enough room to hang fully extended if possible. For travel, fold the gown in tissue paper with as few folds as possible and pack it flat in a suitcase rather than rolling it. The pearl beading on the bodice should face up and not be crushed under other items. Light creases in satin can be steamed out carefully on a low setting — do not iron directly on satin. The boned bodice holds its shape well and is not fragile, but avoid compressing it tightly in transit as the boning can warp if packed under heavy pressure.
