Odi wears pretty much only hand me downs from her big sister. But Piper went from an 18 month swim suit one summer, and the next summer (when Piper she was 2) she was in a 4T swim suit. Unfortunately, Odi doesn't grow that fast. At 2 she is only in a 2T swim suit. She picked this one out of about 6 that I showed her. She said it was like Cherry Jam (Strawberry Shortcakes friend) and she had to have this one! I love it cause it is a halter I think my girls look a-dor-a-ble in halters! She went around all day saying "Momma, this is my cherry jam swim suit, not Piper's". Hahaha, this girl cracks me up!
