This dress is made with a cool, airy seersucker material with tiny ventilation holes created through special processing for breathability. The gentle A-line silhouette is breezy and comfortable to wear on hot days. The material is slightly stretchy, so it is easy to move around without restriction. Designed with slightly wider armholes, allowing you to layer it over a t-shirt.
