Absolutely stunning dress from Milla Nova - never worn and no alterations! Bought brand new 3 days after the sample arrived in store. The size on the invoice is listed as XXL. For reference, I typically wear a 14-16 and this dress just barely didn't fit in the back, so I would say this fits more like a 12-14 depending on your body shape. There is TONS of fabric in the sleeves to create more room in the back of the dress if you are a size 14 or 16, and that's what I was going to do with this dress until I found another one that I liked more. It's incredibly comfortable to wear and the movement of the train is incredible. The fabric feels like a textured crepe - very forgiving and hides a lot!
