Spotted: the cutest summer essential. This lightweight sleeveless dress from Rails is full of flirty and feminine details, like the v-neckline, flowy silhouette and a hemline edged with ruffles. We love the button-down front, too, and a drawstring self-tie waistline makes for a flattering fit. And when you swap out boots for strappy wedges, this piece easily becomes the perfect day-to-night dress.70% Rayon | 30% ViscoseHand Wash Cold. Hang Dry. No Bleach
