If you dont like split drawers then any pair of pajama pants will do. If you do like being able to use the restroom without having to remove and then reinstall all of you undergarments then you might like split drawers. These are very nice split or butterfly drawers that I made for Dickens Fair. They have a draw string top so that they can fit almost any size and have a button placket in the front to keep them mostly closed should the wearing find themselves in a partially dressed state. However the placket does not need to be undone to use the privy. They have Battenberg lace insertions and hem and the legs are decorated with a large number of beautiful and useful tucks.
