Brushed twill romper by Express in an olive green shade I would say, it can be difficult to determine by the pics. This is actually a slip-on style with a halter top, surplice neckline with a hook-n-eye closure I showed, two side pockets, a sturdy elastic waist offering a bit of stretch that creates a nice shape, and belt loops and a tie. Again this is a slip-on style so when you have to use the bathroom you have to work the top down, there is no back zipper. Gently loved, only worn once, is machine washable, and lying flat measures approximately 34 inches halter strap to hem, 21 inches armpit to armpit, and 17 inches at the elastic waist. So please in considering this piece allow yourself some wiggle room for when you’re out and you have to pee. Otherwise it’s a really cute piece for a hot summer day.
