I am in the medium of this dress and it runs generously! Size down if you don’t need the length. Also we gotta talk about how sheer it is. Yes it’s sheer as you can see. I didn’t wear one here but when I wear it out of the house, I pair a cheap little slip underneath. I’m telling you a $15 polyester slip will last you forever and will be used so many times. I wear a bandeau — well not here bc I lazy — or a strapless bra. #LTKunder50
