The Tulum Maxi Dress is the kind of piece that does the heavy lifting for you—throw it on and you're instantly resort-ready. Cut from 100% organic cotton gauze that's impossibly soft and slightly sheer (just enough mystery, not too much), it features a signature low back and raw-edge hem that feels intentional, not accidental. The relaxed silhouette works whether you're heading to dinner, the beach, or that spontaneous sunset moment. Available year-round in multiple colorways, this 9SEED bestseller has earned its place as the dress you'll actually reach for again and again.
