It took me so long to figure out which size to get, because of the reviews. The reviews mention it runs small and others say it’s true to size 😭. We all know FN doesn’t give your coins back. So I went up a size to be on the safe side. I’m 5ft and 155lbs. My waist is 30in, hips 43in and bra 34C. My regular size is a medium, but I chose to size up to a large. I could have actually gone up to an XL, that’s how fitted the dress is. If you want it to be FITTED order your regular size or a size up. If you want some wiggle room go two sizes up. I like the dress, but I wish I got the XL. I think the XL would still hug my curves, but I would have breathing room and not have to be conscious of my stomach poking out after eating. FYI the large fit me like the model.
