Long Sleeve Formal Dresses That Radiate Sophistication Year-Round

Sleek, striking, and endlessly wearable—Windsor’s long sleeve formal dresses are your go-to for polished glamour at any celebration. From garden weddings to city rooftop galas, these styles bring the perfect balance of chic coverage and undeniable allure.

Explore curve-hugging mermaid gowns, flowing maxis, and body-skimming columns designed with thoughtful details like open backs, sweetheart necklines, and figure-defining ruching. This collection reimagines eveningwear with sheer mesh sleeves, off-the-shoulder silhouettes, and lace-detailed bodices that elevate every entrance.

Prefer something breathable for warmer settings? Lightweight chiffon and stretch knit long sleeve dresses ensure you stay cool without compromising on style. Shades like timeless black, bold red, forest green, and crisp white deliver seasonal elegance that transitions from sunset ceremonies to late-night dancing.

Need a little edge? Go for cutouts, high slits, or dramatic bell sleeves that turn heads at black-tie events and formal celebrations alike. Whether you’re styling for a wedding, military ball, or evening soirée, these long sleeve formal dresses blend sophistication with statement-making flair.

Discover the full collection online, in-app, or in-store at over 350 Windsor locations—and find your next wow-worthy look, sleeve and all.
