Got the XS/S and it runs very large. I'm usually on the fence between sizes generally and it runs bit. I just had the sides taken in and it's totally fine. Great easy summer dress.

... it just didn't work for me. The dress was too big on me and was slightly see-through. My fiance's words were "you want to wear a nightgown to dinner?" The dotted pattern and ruffle hem were so cute, but you could see through the dress and it ran large. I'm 5'7" and I'm typically a 4-6 in dresses. I ordered an XS/S in this dress and it still felt too big.
