My son was thrilled with these overalls. He is a thin,  long waisted 11 yo. I ordered a size 14 -based on the size 12 overalls of a different brand he has already outgrown- the body length fits well with some room to let the straps out for growth. The legs are way too long at this point. We are rolling them up. These Dickies Big Boys Duck overalls seem great so far. They are holding up well, and that makes me happy.
