Size: 38 French. This is a bit slimmer fitting with not as much stretch as some of the other dresses, this would fit a US 6, could also work for a US4. NOTE: The undershorts are not attached (but they are included). They are the same color as the dress. Never worn. There is no build in bra. Lacoste's tennis dress is perfect for on court, and it's cool enough to wear after a match, too. Made from sweat-wicking stretch-jersey that allows for a full range of movement, it's detailed with a fluttery mini skirt that's underpinned with briefs for coverage whilst you're serving and volleying. The crossover straps add a joyful pop of color.
