NOT extra large [SEP] This is definitely not extra large.  It's just your standard, run-of-the-mill shower cap that can be purchased at any local pharmacy or grocery store, and frankly, it's not even the best of those that I've tried. The elastic is loose and lets in a good bit of moisture (and I have a pretty big head, so the fact that it's loose on me should say something).  If you are looking for a truly extra large shower cap, look for the simply elegant extra large shower cap with a drawstring sold on Amazon as well!  It is a big haired girl's dream come true.
