About the Dress: Portia & Scarlett XO354

The Portia and Scarlett XO354 is a long, strapless fitted gown built around a heavily beaded corset bodice and a stretch-satin skirt. The bodice is covered in beading and hot stones, with visible boning channels that hold the structure in place. The skirt is smooth and close-fitting, with a high front slit that opens as you move and a short train at the back. The back is fully open, bare from the shoulders to the lower back. This is a bold, body-conscious prom gown available in Black, Lt. Blue, Lt. Pink, and Periwinkle.

Fit & Silhouette

The XO354 is cut to follow the body closely from the bust through the hips and down the length of the leg. It is a true fitted silhouette — not a fitted flare, but a sleek column that stays close all the way down. The boned corset bodice gives strong structure at the top and keeps everything in place through a full evening of wear. The high front slit adds ease and a lot of movement when walking. This dress is designed to look best on someone comfortable with a close fit and an open back.

Fabric & Detail

The bodice is heavily beaded with what the Portia and Scarlett images show as a combination of beading and hot stones set across the full corset panel. The boning channels are visible through the beadwork and provide internal support without needing a separate bra. The skirt is stretch satin — smooth, slightly stretchy, and fluid through the leg. The stretch in the fabric is what makes a close-fitting skirt like this comfortable to walk and sit in. A short train adds just enough length at the back to give the silhouette a formal finish.

Key Features

  • Strapless, structured corset bodice with visible boning channels
  • Full beading and hot-stone coverage across the bodice
  • Stretch-satin skirt — close-fitting with built-in ease
  • High front slit for movement and legline visibility
  • Fully open back — bare to the lower back
  • Short train
  • Available in Black, Lt. Blue, Lt. Pink, and Periwinkle
  • Sleeveless, no straps

Style & Occasion

The Portia and Scarlett XO354 is designed for prom and formal events where the look needs to make a statement. The open back and front slit make it one of the most striking options in the XO354 lineup — this is not a safe choice, it is a confident one. It works well for evening galas and formal events where a body-conscious, fashion-forward silhouette is appropriate. For wedding-guest occasions, it suits evening receptions and black-tie affairs best, where the open back and high slit read as elegant after-dark dressing. The available colorways give you real range: Black is the most dramatic, Periwinkle is unexpected and memorable, Lt. Blue is soft but still striking, and Lt. Pink gives a warmer, feminine tone. Pairs well with strappy heeled sandals, minimal jewelry, and an up-do to keep the open back visible.
