I bought extra outfits because I never want to go back to what I used to think was great sleepwear. Only complaint is that Jockey doesn't make more sleepwear with this fabric. When I see a new one on the website, I buy 3-5 extras to just keep in a drawer for 'someday.' I have literally only worn my Sleep Smart outfits since I discovered them a year ago and they hold up great to the nightly wear and frequent washing. Can't say enough great things about this line.
