6 Lightweight Summer Dresses

Finding a lightweight summer dress that actually works is harder than it sounds. You want something that breathes, flatters, stretches, and somehow still looks polished when you step outside in 90-degree heat. Most dresses are either too stiff, too clingy, or way too wrinkle-prone the second you sit down.

A great lightweight dress should feel soft on your skin, move with you, and keep you cool without requiring a backup outfit by noon. Bonus points if it can handle travel days. That’s where the SPANX AirEssentials fabric comes in: breathable, stretchy, ultra-soft, and built for summer movement.

Below, we’re spotlighting six lightweight summer dresses from our AirEssentials collection that hold up in the heat—and hold their shape while they do it. Each one feels like a breeze, looks effortlessly put-together, and works for everything from airport runs to outdoor weddings.
