7 year old (who normally wears a medium in tops & 8H in bottoms) is wearing an 11/12 and could probably use the size 13/14 for more room in the rise, however the legs would probably be too long. I did cut the mesh liner out cause it waS riding up and the rise was too short with it in. My son complained the liner was uncomfortable and it was causing the suit to pull down exposing his crack! Removing the liner improved the fit in a big way and now he loves it. So, I would buy these again and remove the liner because I don't like the huge baggy boys swim suits currently on the market and I don't like the skin tight "jammers". After tons of searching for years, these are the best we've found, thats why they get 4 stars. We have the dark blue tiki style and love the color. Hes worn them a ton with very little fading/pilling.I read the previous reviews and knew to buy a size up. I was not expecting the shorts to still be on the smaller side though. I have a very solid 5-year-old and these will probably not be worn next summer unless he has a major growth spurt up and starts to thin down. The material seems to hold up well. We have been using the shorts for swimming lessons, so it's a chlorinated pool that we're spending a lot of time in. Soon, we'll be vacationing and it will get a lot of sun exposure as well. I just bought the matching reversible hat that goes with this because we've just had good luck with this brand and the style. I'll update this review in the near future, after our vacation.Nice bright color looks just like the picture. Son is going on a shark dive for his 14th bday, so this is a perfect gift! The fabric is like the shirt, dry wicking fabric. Has a drawstring waist tie so they will stay up. My son wears a 12 slim and I got the 13/14 so they would not be skin tight. Just hope they look okay when wet!Seems like these will be good for my son in 2 years maybe. They are fairly big on him. I suppose he is a skinny little creature for being almost 3 years old. I can't speak to how well they do in the water yet.Very goodWe leave near the beach and go often. My 5 year old starts to complain after 30 minutes in the sand and water that his trunks are chafing. These are a very soft material that dries quickly. Not too long or too baggy. Really good quality. I will be looking for another Tuga suit next season.These are so cute!! I bought these for our summer vacation where we spend most of our time at the beach. My son loved these! All of his other ones would hold sand in the net causing a rash on his upper thighs. These did not at all! Well worth the money & they looked amazingly cute as well :)My son loves the pool and the traditional board shorts were chafing, so I tried these. Love the look and they held up well. However, I got several colors, and some faded and changed color significantly (blues and greens in particular).
