If your little is between sizes size up. My little one is thin and long. She wears 2t but needs 4 for length but since Baileys doesn’t have adjustable waist we went with 3t and they fit with RTG in the waist but are shorter than we’d like. She can’t wear above her waist like she prefers or else they look so short. Pictured here she wearing right at waist level and you can see they are just long enough
I absolutely love these pants and my 8 month old did too I think she looks like a little diva in them! So cute.
