What happens in your pants stays in your pants? Hardly. Our Sin City Jammies are made for fun and frolic, not necessarily sleep. Made of soft-knit cotton, they're plenty wearable in Vegas, Atlantic City, Tahoe, Reno, various Indian casinos and, of course, at home. (May not be appropriate for church camp.) The pants and shorts are detailed with a soft-wearing drawstring waist. Women's sizes.
