I most often fit into a size medium. based on prior reviews, i ordered this dress in a small and it fits perfectly. it drapes nicely. the fabric is soft and flows well. the under layer has a nice little stretch to it. the dress looks good with and without the belt. my favorite and most-slimming look is to just tie cinch and tie it in the back, such that it does not wrap around the front at all. the dress is so comfortable and the neckline is very flattering. no bra needed for my small bust.
