The Colette dress comes in sizes XXS to XL. I’m wearing a medium for a close but very comfortable fit. I wouldn’t size up because then the dress would be too large for me in the bust. There is no snap closure at the neckline, but it stays put nicely for me. I’m wearing the dress in neutral, but it also comes in a slightly darker honey. LTKMidsize LTKStyleTip LTKVideo
