In a report released last week, the YWCA said that women and girls are way too worried about being beautiful. For example, more than 80 percent of the women polled said they were unhappy with their appearance. And our obsession with looking good isn't only costing us our happiness–it's costing us money.

Among the make-you-think statistics the report included was this tidbit: if women put the average $50 that monthly manicures and pedicures cost into a retirement account once a year, they'd save almost $10,000 in a decade. Shocking number, yes. (Personally, I'd rather give up my three-day-a-week Starbucks habit, though. It would save me about the same amount). I'm curious: which $50-a-month beauty fix could you go without for ten years...if the reward was ten grand?
