Do the clothes run large, small or true to size? Any advice for stocking up on summer sale items (for summer 2014)? I know I'm taking a huge gamble since my LO isn't even born yet (due August 30th), but they have the cutest stuff on sale right now for great prices so I definitely want to buy a few things for next summer that I wouldn't have bought at full price.

I'm thinking the 12-18 month size is a safe bet unless the clothes run really large? Does anyone buy there frequently who can comment?
