This dress is the cutest ever!!!! The tutu part is full and the rosettes are adorable! I ordered a size 3-4 for my 2 1/2 year old daughter who normally wears 2T. It has little stretch and its sort of long, but it is beautiful regardless.

Updated to include that the size 3-4 also fit my average size 4 1/2 year old who wears 4T just for reference. The only difference was that the length was obviously shorter than on a 2 year old.
