My 14-yr old daughter found the instructions to make a pair of wrap pants in my old copy of Make it with Mademoiselle
. The project from start to finish took about an hour and a half to two hours. She also made a pair out of stretch denim. This pair is made from knit pique.
EDITED TO ADD:
These are made with stretch denim, elastic in the waist, and a button fastener. We cut the side panels too thin the first time, so we added contrasting panels to extend them. She wears these all the time!
