I'm a big fan of Melody Leotards. Prices are good, as is the quality. It is a small, privately-owned company and the owner (Melody) makes returns easy (doesn't charge extra fees for returning/shipping) and I've even heard that she will make "custom sizes" for difficult to fit kiddos. If you email her your daughter's measurements and tell her about the problem you have finding something that fits her in the shoulders, I'm sure she will be able to help you.
