Most of the costumes I've looked at go from 12-24 months then the next size up is small 2T-4T. DS just started wearing 24 month clothes. What size costume should I order?
I would take him to a store (old navy, walmart, target) and hold up a costume to him. My DD1 needed a 4-5 last year because she is so tall (she was 3). DD2 is wearing a torso costume this year and I think it is a 4, but it goes to her knees.
