I was super nervous to buy this at first with the new ONE size fits all but my daughter LOVES it & it fits great. My daughter is 11 and she is currently an AXS/AS in the top and an AS in the bottoms, which we also bought. It is so cute on her - I wish I could leave a photo with this review. This might be her new favorite Tiger Friday set and I love that she will never grow out of it since it will fit her until she's an AL.
