Description
About the Dress: Portia and Scarlett XO304
Portia and Scarlett XO304 is a fitted mermaid gown built around a deep V-neckline, pearl and crystal hotfix beading, and a dramatic open back. Thin spaghetti straps frame the neckline while the body-contouring silhouette hugs from bust to knee before flaring into a sweeping train. It is available in Black, Champagne, Periwinkle, Peacock, and Pink.
Fit & Silhouette
XO304 is a true mermaid: it fits closely through the bust, waist, and hips, then flares out below the knee. There is no front slit — the flare comes from the skirt opening naturally at the hem. Because the fit is body-con from top to hem, sizing up for comfort at the hips is common. The dress closes at the back with straps and the open-back construction, so there is no zip or boned structure to worry about — fit through the bust and hips is the main measurement to check. Portia and Scarlett XO304 runs true to size in most cases, but customers between sizes should size up.
Fabric & Detail
The base fabric is satin with a smooth, luminous finish and enough stretch to support the body-con cut. Pearl and crystal hotfix embellishments cover the bodice densely and scatter down the length of the skirt, giving the dress a fully beaded look from neckline to train. The beading catches light well under both daylight and event lighting. A gathered detail at the lower back hip area adds a subtle sculptural note without adding bulk. The train flows from the hem and is manageable for dancing — short enough to work on a dance floor, long enough to photograph well.
Key Features
- Deep plunge V-neckline with thin spaghetti straps
- Fitted mermaid silhouette — tight through hips, flares below the knee
- Pearl and crystal hotfix beading — dense on the bodice, scattered on the skirt
- Fully open back to well below the waistline
- Sweeping train at the hem
- Satin base fabric with a sheen finish
- Available in Black, Champagne, Periwinkle, Peacock, and Pink
Style & Occasion
Portia and Scarlett XO304 is built for prom, pageants, galas, and formal evening events where a statement gown is expected. The combination of a plunging V-neck, open back, body-con mermaid cut, and all-over pearl beading makes it a high-impact choice for any high-formality occasion. For shoes, a strappy stiletto or pointed-toe heel in metallic or nude works best — anything that extends the leg line. Keep jewelry minimal: the beading does the work, so small drop earrings or studs are enough. If you are wearing Champagne or Pink, a warm gold or rose-gold accessory complements the palette. Periwinkle and Peacock pair well with silver or platinum tones. Black is the most versatile colorway for accessories. The open back means a standard bra does not work — a low-back solution or built-in cups is the way to go. Marlas Fashions is an authorized Portia and Scarlett retailer and every XO304 is inspected before it ships.
