Nordstrom's next big product rollout is apparently going to be pre-stained underwear for men and women. You get a selection of different kinds of stains which you can select for a customized finish.
For the tee shirts, you can get pit-stains along with your choice of coffee, mustard, ice cream, and/or spaghetti sauce on the front. For the briefs/panties, you can get fake poop and/or urine stains along with menstrual leakage for the pretty ladies, and spermatum blasts for the discerning gentlemen.
All stains are guaranteed not to ever fade or wash out for the life of the product. I heard that you can preorder at the Nordstrom website for $99 per set, one top and one bottom.
