Review on Rokka&Rolla Boys' 4-Way Stretch Board Shorts Swim Trunks with Mesh Lining, UPF 50+: Ultimate Comfort and UV Protection! by Daniel Aboubakar

For people with kids to help with the sizes: My son just turned 4 years old he's quite tall (90% on the chart) so he wears a size 5. I ordered him a small. They tie well enough to fit his small waist. I would say if your child is of average height and 4 years old, buy the XS. If it's between a size 5-6 I would go for Small. The colors are excellent, the quality is excellent, the purchase is successful.
