Basketball Pants

Okay, this is the deal: My sister-in-law asked me to make my nephew 5 pairs of pants for fall/winter, and I would love to get them done as soon as possible. The only thing is I need to find a pattern that fits him. The ones pictured below were made to see how they fit. These pants are now sitting in an envelope waiting to be mailed to my mother so that she can tell me about the fit, but she won't see Nephew until Sunday. Afterwards, Nephew can were these as pj pants.
