Collection: Plus Size Prom & Formal Dresses

Plus Size Formal Dresses - Flattering, Elegant, Confident

Every body deserves a dress that feels amazing. Our plus size formal dresses collection brings together elegant styles chosen for flattering fit and real comfort - for prom, weddings, galas, and formal nights out. Shop A-line gowns that glide over the hips, empire-waist styles that highlight your favorite features, and fitted dresses with stretch and structure in all the right places.

Fits that work for you

Look for details that make a real difference: supportive straps or sleeves, defined waistlines that create shape, and fabrics with a little give that let you sit, eat, and dance in comfort. Sequin and beaded bodices draw the eye up, flowing chiffon skirts move beautifully in photos, and rich colors like navy, burgundy, emerald, and black look elegant at every event, day or night.

Many styles in this collection are available up to size 16, and every dress page includes a full size chart. Please order by your measurements, not your everyday size - formal sizing is different, and the size chart on each dress is the best guide. If you are between sizes, the larger size is usually easier for a tailor to adjust. Orders are processed in 1 to 3 business days and shipped within the US, with free US ground shipping on orders over $299. Browse the collection below and choose the dress that makes you feel like the best version of yourself - because that confidence is what people remember.

What sizes do these dresses come in?

Sizes vary by dress, and many styles in this collection go up to size 16. Check the size chart and size options on the dress you love before you order.

Which style is most flattering?

A-line and empire-waist dresses flatter most body types because they define the waist and flow over the hips. Fitted styles with stretch fabric are also a great, comfortable choice.

How do I measure myself?

Use a soft tape measure for your bust, waist, and hips, then match those numbers to the size chart on the dress page. Measuring takes two minutes and prevents most size problems.

Can I return a dress that does not fit?

Yes. Returns are accepted within 5 days of receipt for full store credit, following the return policy on our site. Keep tags attached until you have decided.
