Whether you want to be a true style monger or are just avoiding the dreaded VPL, thongs are mandatory for girls with high thresholds of pain. Whether you're obsessed with Hello Kitty or just a fan of ass, cleavage here is where to get the goods.

However, G + G does have a wealth of pretty underwear, from lacy boy shorts to cartoony briefs. Colorful thongs featuring Hello Kitty and Felix the Cat are always in stock. The best part is that these cute unmentionables can be had for under $5 each.

This South Street mainstay for horny couples and kinky loners is known for its toys and sexessories. Amongst all this sophisticated get-off gear are racks of festive undies -- from wispy Valentine's draws to saucy joints that scream "spank me!" to stripper friendly thongs in sparkly durable spandex. For the more demure, there are also cotton skivvies from Hustler.

Oh, the joys of off-priced shopping never end with this pseudo-European take on Marshalls. While perusing the store for designer finds can be an exercise in patience, Daffy's supplies silky thongs at a sexy price. Brands such as Victoria Secret and La Perla can be found hidden among the random unpronounceable European labels, so just bring your bargain-hunting eyes.
