Description
About the Dress: Portia and Scarlett XO173
Portia and Scarlett XO173 is a long strapless sweetheart corset gown in hot-stone tulle with a tiered ruffle skirt. The bodice is boned and fitted, the skirt is built from tiered ruffles, and the gown finishes with a high front slit and a sweep train. A matching choker scarf is included as part of the look. It is available in Pink, Mint, Red, and Black.
Fit & Silhouette
XO173 is a fitted, sleek silhouette from the strapless sweetheart neckline straight through the hips. Below the hip the tiered ruffle skirt opens up and builds into the sweep train. The high front slit adds movement and length to the leg line. The boned corset bodice holds its shape throughout the night without needing a strapless bra, and the crisscross lace-up back ties allow you to adjust the fit across the torso after ordering. Portia and Scarlett XO173 runs true to size; standard sizing from 00 to 16 is available.
Fabric & Detail
The base fabric is tulle layered with hot-stone embellishment — small faceted rhinestones set across the bodice that catch and scatter light as you move. The tiered ruffle skirt layers multiple cuts of tulle to create volume and texture from the hip to the floor. The sweep train extends the back of the skirt slightly past the hemline. The crisscross lace-up back is both functional and decorative, running the full length of the corset and finishing with a tied bow. The matching choker scarf that ships with the gown can be worn loosely around the neck or draped across the shoulders.

Style & Occasion
Portia and Scarlett XO173 is made for prom, formal evenings, and evening events. For formal evening events, pair it with strappy heeled sandals and minimal jewelry — the bodice does the work. The included choker scarf adds a fashion-editorial element that photographs well under event lighting. The high slit works best with a thigh-high or seamless undergarment. Colorway choice: Pink and Mint read softer and more romantic in photographs; Red and Black photograph as bold and high-contrast. All four colors are rich and saturated in person. It is offered in Pink, Mint, Red and Black, 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
The XO173 combines three features that rarely appear together on a single gown: a fully boned hot-stone corset bodice, a tiered ruffle tulle skirt, and a high front slit with a sweep train. Most fitted prom gowns either lead with an embellished bodice over a simple skirt, or lead with a dramatic skirt over a plain top. XO173 does both simultaneously — the bodice is densely set with faceted hot-stones that catch light from every angle, and the skirt is built from multiple tiered layers of tulle that create genuine volume and movement rather than just sitting flat. The high front slit breaks the fitted silhouette in a way that adds mobility without changing the overall slim line of the gown. The sweep train extends the visual length of the skirt from the back, so the dress reads as long and dramatic from every angle — front, side, and walking away. The crisscross lace-up back is another distinguishing detail. It is not just decorative; it is a true functional closure that you can tighten or loosen to fit your torso exactly, which matters when a corset bodice is this structured. Many gowns with lace-up backs use a zipper underneath and treat the lacing as decoration only. On XO173 the lace-up is the primary closure. Finally, the included matching choker scarf is a finishing piece that ships with the gown, not an accessory you need to track down separately. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise. Popular colorways of the XO173 sell out quickly each season, so early orders get first pick. Our stylists fit the XO173 in the boutique every week and know exactly how it runs.
The crisscross lace-up back on the Portia and Scarlett XO173 is the primary and only closure on the gown — there is no zipper underneath. The lacing runs the full length of the boned corset from the top of the bodice to the waistline, threading through a series of loops and crossing back and forth as it moves down. At the bottom it ties off in a bow. Because it is a true lace-up closure, you can adjust the tension across the torso after the gown arrives. If the bodice feels slightly snug across the ribs, you loosen the lacing; if it feels loose after weight fluctuates before the event, you tighten it. This gives you a few inches of real adjustability without going to a tailor, which is a practical advantage if you are ordering several months before prom. The adjustment range is not unlimited — the gown is sized to your measurements first, and the lacing handles fine-tuning. We recommend ordering your standard size based on the size chart and using the lacing for the final fit. If you are between sizes, size up and use the lace-up to bring the bodice in. Sizing down is harder to correct with lacing alone. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise. Popular colorways of the XO173 sell out quickly each season, so early orders get first pick. Our stylists fit the XO173 in the boutique every week and know exactly how it runs. Order the XO173 early enough to leave a week or two for a tailor to fine-tune the fit before your event. Standard delivery on the XO173 is 7 to 12 business days, with rush processing available on request.
The four available colorways — Pink, Mint, Red, and Black — allow a group to coordinate in a single color or mix two colors across the court. A common approach is to have the principal wear one colorway (for example Red) while the court wears another (for example Black or Pink), creating a clear visual hierarchy on stage or on the dance floor without changing the silhouette. Because the gown is offered in sizes 00 through 16, it covers a realistic range of body types within a group without needing to source from a second designer. When ordering for a group, we recommend placing all orders at the same time so the colorways come from the same production run and the dye lot is consistent across all dresses. Contact us before placing a group order and we can confirm current stock levels across the sizes and colors you need. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise.
Portia and Scarlett XO173 runs true to size for most shoppers. The gown is available in sizes 00, 0, 2, 4, 6, 8, 10, 12, 14, and 16. To measure correctly, take your bust at the fullest point, your natural waist, and your hips at the widest point. Compare all three measurements against the size chart and order the size that fits your largest measurement — the lace-up back closure gives you adjustability across the torso once the gown arrives. The boned corset bodice has very little stretch, so if your bust measurement puts you in one size and your waist in another, go with the bust. A tailor can take in the waist of a boned bodice, but letting out the bust of a boned corset is significantly more difficult and expensive. If you are between sizes or have a longer torso, sizing up is the safer choice. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise.
The boned corset bodice on the Portia and Scarlett XO173 provides enough internal structure that most wearers do not need a bra. The boning holds the sweetheart neckline in place and supports the bust without external help. If you prefer additional support, a strapless adhesive bra or a silicone modesty panel works well under the structured bodice. For the bottom half, the high front slit means your undergarments will be visible when you walk or sit. A thigh-high stocking or a seamless high-cut brief in a tone that matches your skin or the dress colorway is the cleanest option. Avoid shorts or bike shorts under this gown — the tulle layers of the skirt are light and can bunch around added undergarment layers, which affects how the ruffles fall. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise. Popular colorways of the XO173 sell out quickly each season, so early orders get first pick.
Yes, the XO173 can be hemmed for height by a local tailor. Because the skirt is a tiered ruffle in tulle, hemming from the bottom is straightforward — a tailor removes material from the bottom hem of each tier proportionally. The sweep train at the back will also be adjusted as part of the hem. For petite wearers, we recommend having the alteration done after the gown arrives so the tailor can pin it to the exact length you want with the shoes you plan to wear. Allow at least two to three weeks before your event for alterations. The corset bodice can also be taken in at the waist by a skilled tailor if needed. We recommend going to a formal wear specialist rather than a general tailor for any work on a boned bodice, as the internal structure requires specific handling. Every XO173 order is hand-inspected before shipping so the fit and finish arrive flawless. If you are between sizes on the XO173, send our team your measurements before ordering and we will advise.
