Runs very short in torso area
Size: 2T, Color: Mauve/Butterflies
I bought 2T and the shirt came down to daughters belly button. She’s 21 months and I compared it to all my other 2T shirts and these were way shorter so it’s not that my daughter is just big for her age. These run extremely short in the torso.
