It seems that most comments have been that the suit runs small. From the sizing chart provided my son would be a size 8. So do I buy a 10????

I have bought 4 suits (grandsons) and they were all correct sizes, however the white shirts that come with them are small. The white shirts size 6 (I bought 2) were fine, but the white shirts size 4 (I bought 2 of these also) were small. One of them was tight around the neck and so it was very hard to button. Grandson kept unbuttoning it because it was to tight. The shirts were also a little short at the bottom so not much to tuck into the pants. I hope that helps.

I ordered my son the exact size he was....a 2T. The waist is thin but had elastic. If he's husky I'd go a size bigger. The measurement chart helped alot

I would follow the measurements on the sizing chart. My son is normally a 3T but according to the sizing chart his measurements indicated we needed a 4T. I'm glad I measured because the 4T fit perfect.

Hi Karry, I wore the same suit (size 9 ) at about 160 lbs. I am thinking you are probably between a 9 and 11. Amazon is so good about returns. I might suggest ordering an 11 first. Hope this helps:)

Hi Danielle, my son is a pretty big 4 yo. 4T i too small. He wears mainly size 4 in little boy clothing now. Based on the other review (a 6 yo who wore a medium 8-10), i ordered the size small. I hope it works out! I'll post a review once it comes in.

Yes, it runs small. I ordered a 7-8 for when my son was 5 year olds and it was just a little big. He was about 42 inches at the time. Hope this helps

I used the size chart next to the order sized field. I chose LARGE for my boy per the numbers in the size chart, i.e. chest, general size, waist and sleeves. After trying it on, my son and I come to to same conclusion, too tight and the sleeves were too short. I could have re-order XL, but since I have to pay shipping both way, I didn't want to take more chances. This trying experience costs me $30 in shipping and I am still waiting for my refund.

Hi Jennifer, rather than basing it on my child's weight, I looked at the O'neill site and actually measured my child based on their sizing of chest, waist, etc. I found that she was in between two sizes based on these measurements so I got the larger so she could grow into it. And it happened to not correlate with her weight. The suit is thick and has a decent stretch to it, but the only thing to make sure when measuring is also the height (more so than weight), so that the suit does not tug in the crotch area or end up hurting once it's fully zipped. I hope this helps!

I will try to get them from my grandson who is 9 and slender... not skinny just not above slender.... he was wearing 8-10 when I ordered and the site said that's small... noo small is way to small.... ordered the medium and it fits perfectly... these run very small compared to clothes usually buy so I'd buy at least one size up.... even my seven year old couldn't fit the small... so the 8 and 10 both wrong.... we were satisfied with the medium... the price is right and the quality was comparable to the more expensive ones you buy from Dick's and other sporting goods stores good luck

Have just checked with my daughter. For her shape the top was a bit tight and the bottoms a bit big. The bottom's drawer string helped. We really can't remember whether we went with sizing chart. 6 months ago now. Swim suit still in great nick after lots of use. Hope this helps.

I just seen the one that said size small and size youth med..... They just run really small my son that just turned 3 has the small size he was able to wear it last Halloween and will wear this Halloween then wont be able to wear it again the pants run small.ANd i think he's size said made to fit a 3-5 year old but no way is that true. My sons med wouldnt fit an 8 year old like it says. might fit a petite slender 7 year old. Makes a nice costume. My son was just excited to get a helmet so then i dontated the rest of the costume so someone else could have it instead of sending back.

Claire: We've had special orders for 4 and 5 year olds and jerseys came out nice. Everything has to be scaled down and the back name has to limited. If you have the time, please write back and let me know how wide you want the jersey, length of the sleeve from the shoulder seam to the wrist and length of the jersey. I would get recommend getting something a little big for him now so he can grow into it. Once we start the project, you can not cancel the order since it would be a special order. thanks Carl

Please note that this swim suit is in Asian size. Since every manufacturer using different sizing chart during production, it might cause some size difference. The size in Asian is smaller than in US. If you are interested in this item, please do not hesitate to contact us with your Amazon email, we will be always around for you. Hope this will help. Thank you!

Hi Debra, I purchased a size 10 and my son is 9 years old with a slightly smaller build...so I would probably go with the next size up which is I believe a 12. Hope this helps. Good luck. Celia

There is a size chart however I do remember it being hard to find. I have an 8 year old son myself and he wears a Boys Large just fine.

Hi! I left an image in the customer images section with the size chart! I believe its in international system measures, but you can google the conversion for imperial and check the best size for your son! Best wishes

Hi I purchased a medium for my daughter she is 11 but very small so she where's about 8-9 pants and 10 shirt. The jacket is a little large but I wanted it that way as the sleeves are banded so you can pull them in. As I want her to get a bit of wear out of it. I would say the jacket would be more a 10 fitting. If your child is an 8 are they big or small? Do you want growing room? I love the jacket it was just what I wanted, I purchased the Large for my son and he wears a 12 pant and 12-14 shirt the jacket also has just enough growing room. I hope I have helped you with your sizing&#128522;

It runs really small. My daughter is 5'4", 160 and it wasn't even close. We ended up buying the sea wetsuit in xl. Hope this helps.

I would guess a size 3 would work well but buying a 3 and/or 4 and trying it is the best way to find out, and return the one you don't take of keep them both if the 3 fits and you have the 4 for when he grows into it. Otherwise return both, but the other answers are correct to look at the O'Neill site and make sure the height is right. If it is too loose it will let cold water in and circulate, if it is too tight it will be very painful and useless. It is a great wetsuit for the toddlers, best I ever saw. BD
