I bought this for my almost 4 year old daughter who said that the pool was too cold for lessons and refused to get into the water. We live in the Midwest so the winter will be cold but the pool is indoors and heated so it''s mostly when she''s sitting on the side waiting for her turn. She loves this and couldn''t wait to show it off. It''s light enough that she can move in it but it keeps her warm so that she doesn''t think about being cold and can concentrate on her lessons. This was just what we were looking for.
I did mark "feels too big" as I had read that the sizing was a little off and bought a size smaller than I would''ve normally. She wears a 4 so I went down a size and it fits her great, snug but with enough room to move and grow about another inch before she needs the next size.

I got this for my daughter to help her in colder water for the summer. She is thin for her age so I got a size smaller and it was still a bit too big for her. She loved it though and it did well to keep her warm and happy. It runs a bit big, but overall a great buy.

Fits well now and looks to allow a year's growth.  Quiet colors but for girls only.

The kiddo was borderline hypothermic whenever she went to swimming lessons so I thought a wetsuit would help.  Even though she is 3 years old, I'm glad I went with the sizing chart recommendation of 2T.  Now she can get through an entire lesson without turning blue!
