I ordered a medium because that’s what the website recommended. I am normally a small and that is what I should’ve ordered. I did have this dress altered to fit me. So this dress fits a small, even though it says medium. So if you are normally a small, I guarantee that this dress will fit or you can return it. I wear a size 4 in pants and I’m 5’8. If you want the belt, I can include that with the dress as long as you don’t request a lower price. The belt was $100.
