I believe we bought a size 10 and my son was 9. He kind of drowned in it, but he loved it. He can always grow into it

I ordered two of the Child size Large, for my 7 and 10 year old kids. They are average sized  --it fit my 7 year old perfect, but was a little small on my 10 year old. Probably should have ordered an adult small for her, but either way it will work for a while. Good quality -highly recommend!

I think my son will love it. However he usually wears a 12, and the large size seems like an 8. I'm trying a xl and xxl to see if they work. Otherwise nice quality, thick and soft.

My son wears a size 10, so I purchased the 10-12 vs 8-10 and it was too large.  The drawstring allowed me to tighten to have him wear for an event, but won't likely grow into them for another year.  Suit legs are longer than in photo and hit my son well below knee.

Way too tiny , I ordered an extra large, being size 10. I wanted to return it, but never heard from seller.

Bought this for my son and thought the 14-16 size would be good for him, but they run really large. This is really more equivalent to an adult small than a kids large. It was a great deal though, so I'll hold on to it until he grows into it, probably next season.

Youth Large runs very big. My daughter wears a youth size 10 or large and they were swimming on her. Great quality but too big.

Knowing these parkas should be worn big-- after swimming to be cozy and to grow into... I ordered a Youth Extra Large for my son who is 10 years old, a solid 100 lbs and 4'3", it was too small, so I reordered a Adult Small and it fits great. Incidentally, I also bought an Adult Small for my daughter who is 12 years old, 89 lbs and 5'1" and it fits her great too. NOTE: The return shipping was Not Paid by the Seller- was going to be $11-$15 to ship the too small one back, so I sold it to another swim mom. Kids love love love the parkas and I don't have to pay return shipping! Everybody's happy now!

I was unsure of the sizing, and followed the advise of another review, whose child was the same age as my son. He is quite talk for his age, but unfortunately the item is way too large on him. He is almost 5. I will keep the item until he grows into it, as it is really nice otherwise.

Fits my 10 year old fine, but was expecting it to be larger so she could wear it more than 1 year

It says it is a men's large so I ordered it for my teenage son. When it came, it looked like a kids large that would fit at 8-10 year old, not a 15 year old! Don't know what to do with it now.

Love these shows but they run EXTRA LARGE. My 5 year old son is a size 13 . I ordered a 12 considering all the comments about it running big and still the shoes are way too large. Saved them for next year. Should have ordered a size 11.

I bought it for my 7 year old, but my 11 year old is wearing it instead.  I guess I should have stuck with a kid's size.
