If you buy one size bigger for a child! My baby fit perfectly at 6-9 months so I bought a 9 month old swim trunks thinking they would fit. They've gotten MUCH smaller. I wish I had appreciated it because Dad was very excited to be a match for our son. Dad's trunks fit perfectly so I'd say only kid sizes don't fit.
