Finding a short sleeve one piece swimsuit for my preschooler was very difficult. Most of these are for babies and toddlers. We bought two of these and they are used about 5 times a week. They are in good condition and a great price. I bought size 4-6 for my 4.5 year old and it fits well and I think he will outgrow it before he is 6 years old. So I would say go one size up if you are between size 3-5 and 4-6.
