This is an adorable little short set that I bought for my daughter, but it’s a little too small for her. The under arm two under arm is about 16 inches but has some stretch. The waist is about 12 1/2 inches across the front. The length from the shoulder to the bottom of the shorts is 30 inches.Please let me know if there’s any other questions about this jumper that you need to know. There is a teeny little spot at the bottom of the zipper. That was a little worn, but an easy mend.
