Description
About the Dress: Portia and Scarlett XO335
The Portia and Scarlett XO335 is a strapless sweetheart ballgown built around a fully boned corset bodice and a voluminous layered glitter tulle skirt. The XO335 is available in Black, Teal, and Yellow — three distinct colorways that all share the same structured silhouette and beaded sweetheart neckline. This is a full-length gown designed to make a statement on any formal occasion.
Fit & Silhouette
The Portia and Scarlett XO335 follows a true ballgown silhouette: a structured, form-fitting corset bodice that cinches the waist and gives way to a wide, floor-sweeping skirt with serious volume. The strapless sweetheart neckline frames the bust with a clear center dip. The boned corset bodice keeps the gown securely in place without straps, so you can move and dance with confidence. This silhouette works across a wide range of body types — the fitted bodice defines the waist while the full skirt adds drama below.
Fabric & Detail
The skirt is constructed from layered glitter tulle that catches the light as you move — the effect is most pronounced in the Teal and Black colorways, and slightly softer in Yellow. The bodice features visible boning channels that give it structure and support. Beading lines the sweetheart neckline edge, adding definition to the neckline across all three colors. The gathered fabric at the corset bodice front adds dimension to the bust area.
Key Features
- Strapless sweetheart neckline with beaded edge detail
- Fully boned corset bodice with visible boning channels
- Voluminous layered glitter tulle ballgown skirt
- Full length, floor-sweeping hem
- Available in Black, Teal, and Yellow
- Built-in structure and support — no additional undergarments required
Style & Occasion
The Portia and Scarlett XO335 is designed for events where you want the full ballgown effect. It is an excellent choice for prom, formal dances, evening galas, pageants, sweet 16 celebrations, and debut balls. The Black colorway is classic and versatile; Teal brings a bold jewel-tone presence; Yellow makes an impact under event lighting. Style with strappy heeled sandals to keep the focus on the gown — a simple metallic heel in gold or silver works well with all three colors. Keep jewelry minimal: a pair of stud or small drop earrings lets the beaded neckline do the work. An updo shows off the structured bodice and sweetheart neckline to full effect. Steam the tulle layers on low the day before your event so every ruffled tier falls exactly the way it did on the runway.

Frequently Asked Questions
The Portia and Scarlett XO335 has a structured corset bodice with visible boning channels that provide the primary shaping. The back closure on this gown is a key part of how it fits — the boned bodice is designed to hold its shape and keep the gown securely in place across your torso without relying on straps. Based on the images available, the back shows significant upper-back exposure, which is consistent with an open or lace-up style closure, though the full extent of the back opening is not entirely confirmed in the crop provided. If you need specific confirmation of the exact closure type before ordering, our team can pull that detail directly from the designer.
What this means practically: a boned corset-style bodice on a ballgown like the XO335 is typically adjusted by a seamstress at fitting. The bones are sewn into fixed channels, so the bodice itself is not infinitely adjustable the way a lace-up corset back would be — you are fitting to the garment, not pulling it tighter or looser on the day. For this reason, measuring correctly before you order is the single most important step.
To measure for the XO335, you need three numbers: your full bust (measured around the fullest part of your chest), your natural waist (the narrowest point, usually an inch or two above your navel), and your full hips (the widest point, typically about eight inches below the waist). Take all three measurements with a soft tape measure while wearing the undergarments you plan to wear with the gown. Do not pull the tape tight — a finger's width of ease is appropriate.
Once you have those numbers, compare them against Portia and Scarlett's size chart for XO335. If your bust, waist, and hip measurements fall into different sizes, always size to the largest measurement and plan to have the gown taken in by a local seamstress. A boned ballgown bodice can be taken in more easily than it can be let out, so erring up one size is the standard industry advice.
If you are between sizes or your measurements are close to a size boundary, our team can help you interpret the chart for this specific style. Text or WhatsApp us with your three measurements and we will give you a direct recommendation.
The Portia and Scarlett XO335 is a full-length strapless ballgown with a structured boned bodice, a sweetheart neckline, and a layered glitter tulle skirt with real volume. That combination puts it firmly in the category of high-impact formal gowns — the kind that photograph well, work under event lighting, and command attention in a large room.
Prom is the most natural fit. The silhouette, the glitter tulle, and the dramatic proportions are exactly what the prom dress category is designed for. If the event has a formal or black-tie-adjacent dress code, the XO335 will meet or exceed it.
Formal dances and evening galas are an equally natural match. The ballgown silhouette reads as appropriately dressed-up for any black-tie or formal event — school formals, charity galas, dinner dances, and awards evenings all fall into this category.
Sweet 16 parties and debut balls are an excellent fit when the event has a formal or semi-formal tone. The XO335 has the volume and structure expected of a gown for those milestones, especially when the celebration involves a formal entrance or presentation.
Pageants are a strong use case for this gown. The full ballgown silhouette, the embellished neckline, and the glitter tulle skirt are consistent with evening-gown competition rounds at the regional and state level.
What the XO335 is not suited for: casual celebrations, outdoor garden parties, beach weddings, or any event with a cocktail or semi-formal dress code where a floor-length ballgown would be out of proportion. If you are attending a wedding as a guest, the XO335's bold silhouette and glitter finish may draw more attention than is appropriate for a guest — it is a gown designed to be the focal point, which is better suited to events where that is the intention.
For color selection: Black is the most versatile across all the above occasions and tends to photograph very cleanly. Teal photographs with strong color saturation and is particularly effective under stage or event lighting. Yellow is a high-impact daytime or well-lit ballroom choice. If you are unsure which color reads best for your specific venue or lighting, our team is happy to advise.
Portia and Scarlett XO335 runs true to the brand's standard sizing, which follows industry formal-wear measurements. The fit is determined primarily by the boned bodice — the bodice size is the critical measurement, not the skirt, since the tulle ballgown skirt has significant volume and does not depend on a close hip fit.
For XO335 specifically, measure your full bust, natural waist, and full hips as described in the sizing FAQ above. The bodice fit is the priority — if you are between sizes, size up and plan to have the bodice taken in by a seamstress. The waist can be taken in; the skirt volume is fixed by the construction.
If you typically wear a different size in ready-to-wear versus formal wear, use your measurements against the Portia and Scarlett size chart directly rather than converting from a clothing size. Formal gown sizing and retail clothing sizing do not correspond. Our team can help you interpret your measurements for this specific style if you contact us before ordering.
The XO335 has a fully boned corset bodice with visible boning channels, which means it provides its own structure and support. For most customers, no additional undergarment is needed under the bodice — the boning is designed to hold the bust in place and keep the gown from shifting during wear, including dancing.
If you prefer additional coverage or support for personal comfort, a strapless adhesive bra or silicone cups can be worn underneath without affecting the look of the gown. Avoid a traditional strapless bra with a structured back band, as it may sit visibly at the top of the back opening.
For the skirt: the tulle ballgown skirt has enough volume that a simple slip or shorts underneath are optional for comfort and movement. If you plan to dance extensively, fitted shorts under the skirt can be more comfortable than a full slip. No special shapewear is required for the silhouette since the bodice provides the shaping.
Yes, the XO335 can be hemmed, and hemming a ballgown with a layered tulle skirt is a standard alteration that most formal-wear seamstresses handle regularly. Because the skirt has multiple layers of tulle, hemming it takes more time than a single-layer gown — budget for that in both cost and timeline.
If you are shorter than average (roughly under 5'4" without heels), plan for a hem. The standard gown length is designed for a model height of approximately 5'8" to 5'9" with heels. Before your alteration appointment, wear the shoes you intend to wear with the gown so the seamstress can pin the hem at the correct height.
For taller customers, the floor-sweeping length is more likely to work with a standard heel without alteration — try the gown with your shoes before booking a hem appointment. Allow at least two weeks for alterations before your event, and more if you are in a busy season like spring prom.
The XO335 is built for a formal event that includes dancing. The boned corset bodice holds its position throughout the evening without requiring constant adjustment — a significant advantage over strapless gowns without internal structure. The bodice should feel secure rather than restrictive if you are in the correct size.
The tulle ballgown skirt has a lot of volume, which means it moves around you rather than constraining your legs. Walking, dancing, and sitting are all manageable in this silhouette. The skirt does have physical weight from the multiple tulle layers, which is worth noting for a long evening — most customers find it comfortable for a full event, but if you have concerns about mobility, trying the gown on before your event is worthwhile.
For maximum comfort while dancing, wear well-fitted heels that you have broken in before the event. The hem length matters here — if your gown has not been hemmed for your height, the extra length at the front can catch underfoot during fast dances.
Color accuracy in formal-wear photography varies by lighting setup and screen calibration, so it is worth knowing what to expect for each colorway of the XO335.
Black is the most consistent between photos and in-person — it reads as a true, deep black under most event lighting and photographs cleanly in both flash and ambient light. If you want a color that will look exactly as expected in every photo, Black is the safest choice.
Teal photographs with strong color saturation. In person, the glitter tulle adds a luminous quality to the teal base that can appear slightly more vibrant under stage or ballroom lighting than in standard photography. It is a bold, distinctive color that stands out in group photos.
Yellow in the XO335 appears as a warm, bright yellow in photos. The glitter element in the tulle is subtler in Yellow than in Black or Teal, giving it a softer overall finish. Under warm event lighting, Yellow can appear slightly richer or more golden than in daylight photography.
If you are trying to coordinate with a group or damas, Black is the easiest to match. For any color-matching questions, contact our team — we can advise on how each color photographs at different venues.
