One of my sons favorite shorts.

I bought these board shorts for my 6 yr old who is on the smaller side.  He wears 22 in jammers so I bought a 22 but they were way too big.  The front is held together with velcro where a zipper would be and then ties in front to cinch it down just a little more but the string does not loop through the entire waist so the amount one can tighten is limited.  I  sewed the darts in the back down deeper and now they fit fine.
