Description
About the Dress: Portia and Scarlett XO327
The Portia and Scarlett XO327 is a long fitted prom gown with a halter neckline, sweetheart bustline, open back, and a front-center high slit. The bodice is structured with visible vertical boning channels, giving the top a true corset fit. A small train at the hem adds a formal finish. The gown is available in Lilac, Periwinkle, Pink, and Yellow, with hot-stone scatter embellishment across the fabric on select colorways.
Fit & Silhouette
The Portia and Scarlett XO327 follows a fitted silhouette from the chest through the hips, with the skirt flaring slightly toward the hem. The boned corset bodice cinches the waist and holds the shape securely without a separate undergarment. The halter strap ties behind the neck, leaving the entire back bare. The front slit opens from mid-thigh and gives the fitted skirt full range of movement. This is a body-hugging gown — it follows every curve from chest to floor. If you are between sizes, size up for the hips and have the waist taken in, since the corset boning makes the bodice harder to alter than the skirt.
Fabric & Detail
The base of the Portia and Scarlett XO327 is a stretch jersey fabric that moves with the body and recovers its shape. On the Lilac and Periwinkle colorways, hot-stone scatter embellishment catches the light across the surface. Pink and Yellow colorways may carry a different surface finish — check the product listing notes or contact us to confirm embellishment details for a specific color before ordering. The boning is visible through the corset bodice panels, not hidden, which is part of the design. The train is built into the skirt and does not detach.

Style & Occasion
The Portia and Scarlett XO327 is built for prom, formal evening events, and pageant. The open back, front slit, and boned corset silhouette make it a strong choice for anyone who wants a gown that makes a statement from every angle. It reads equally well under ballroom lighting and on a stage. Style it with strappy heeled sandals, minimal jewelry at the ears, and a small clutch — the open back and halter neckline leave the neck and back as the focal points, so less is more with accessories. As a wedding guest, this gown suits evening and black-tie receptions best, where its open back and high slit complement a formal atmosphere. It is available in four colors — Lilac, Periwinkle, Pink, and Yellow — so groups or court members can coordinate across colorways while each wearing a distinct shade.
