I am 5'4 and a standard size m, this dress fit like a dream. The strappy open back that drapes beautifully down to the waist and the high wrap neck has an elegant tie collar that gently flows down the back are adjustable, allowing you to customize the dress to your body and chest size. I have never had issues with this dress riding up or exposing me, you can dance and walk for blocks without constantly pulling it down. Truly the best dress for any event!
