The Celeste Isla
There's a reason a floral formal dress like The Celeste Isla gets saved, shared and re-worn — it's built for your next formal evening.
Cut from airy, softly draped chiffon that moves with you. The a-line silhouette skims gently from the waist, flattering every figure. It pairs a face-framing V-neckline, a clean sleeveless cut, a floor-length sweep for full-evening elegance with a graceful floral motif. Every seam, dart and hem is placed to flatter — so you spend the day celebrating, not adjusting.
Available in 2+ colors including Navy Blue and Black, it's easy to match your palette or dress code. From galas to formal dinners, an evening gown this refined earns permanent wardrobe status — timeless enough to re-wear, distinctive enough to be remembered. Dress it up with heels for the ceremony or down with elegant flats for an outdoor venue — this evening dress adapts. It's the dress you'll reach for again — refined enough for your next formal evening, comfortable enough to actually enjoy it.

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.
