These are a nice looking set of kids swimwear. It fits true to size for the shirts, but a little loose for the shorts (I have skinny boys though). For the price, it's great quality and just as good as similar brand name items.

We bought this for my 9 year old and it was unfortunately way too big. But it was exactly what we were looking for. They did not have the size smaller in the two pack set so we ended up ordering a single swim set that was identical to the brighter blue swimsuit and have been very pleased with the smaller size.Note: this was for my daughter and she hated the netting inside the shorts but that was easily removed with a pair of scissors. Not sure how that would be for boys.

short answer: order at least 1-2 sizes bigger than the size you need.Long answer: Twin Grandsons. I buy/order them clothes 3 times a year for the last 6 years, in store and on line. I know their sizes. They have ALWAYS worn age appropriate size clothing 2 yrs old = 2T, 3 yrs old = 3T, 6 yrs old = 6T or 6/7 (

Bought this set in size 8. Both shirts are the right size. Pants are 10-12 (and could fit a 14 year old). My son really wants this so I ordered a replacement. This time, one of the swim trunks is size 10-12 and the other is 7. I didn't even look at the shirts. Now I had to return AGAIN and my son won't have any swim trunks for when we needed them.

I read a lot of reviews saying they sent random sizes but I’m glad that I received the right sizes (ordered two sets in different styles and sizes) and they were also very good quality. The kids are getting them for the holidays so hoping they fit by then lol
