These are based on this Hollywood pattern. The top I extended to make a top from, and the bottoms are just your basic drawstring.
The dark blue is a great cotton flannel, but the top is 100% polyester! HA! I wanted to use up this icky fabric for something, and i thought this was as good a project as any. I put some nice details in this (bound button holes) so I would wear it. I have been and its very comfy and soft. I love this set.
