The Eden Margaux
The Eden Margaux was designed for the entrance you've been planning — a prom dress that works as hard as you do on the day itself.
Cut from structured taffeta with a gentle rustle and elegant body. The a-line silhouette skims gently from the waist, flattering every figure. It pairs a poised halter neckline, a clean sleeveless cut with a floor-length sweep for full-evening elegance. Fully finished seams, a considered fit through the bodice and a hem that hangs the way it should — the details you notice the moment you put it on.
Available in 3+ colors including Plum, Olive Green and Royal Blue, it's easy to match your palette or dress code. Prom photos last forever — this is the dress that still looks right in ten years. Pair it with strappy heels and let the silhouette do the talking. Dress it up with heels for the ceremony or down with elegant flats for an outdoor venue — this prom dress adapts. It's the dress you'll reach for again — refined enough for the entrance you've been planning, comfortable enough to actually enjoy it.
From Guest & Gown's occasion edit: pieces you'll actually reach for again. Add The Eden Margaux to your cart before your size sells through.

Fabric & Care
Every Guest & Gown dress is fully lined, with an invisible back zipper and enough structure to skim your silhouette — never cling, never turn sheer in daylight or flash photography. The exact fabric of this dress is listed in the description above. Care: cold hand wash or dry clean, and a low-heat steam to release travel creases.
Shipping & Delivery
Your order ships within 48 hours and arrives in 7–12 business days across the U.S. — a few extra days internationally — with tracking emailed the moment it leaves. Attending a wedding soon? We recommend ordering at least two weeks ahead, so you can try everything on calmly.
