Sometimes the biggest confidence booster is concealing something special under your clothes—such as a lit stick of dynamite in your pocket or a tattoo of yourself solving a complicated math problem. Feel confidence against your skin with today's Groupon: for $30, you get $60 worth of lingerie from Biatta Intimates online.
Biatta's online boutique showcases saucy, supportive styles for juniors, plus sizes, and everyone in between. The Liza demi bra drapes the upper body in pink satin lace, with a black ribbon running across both cups ($20). Nab the matching stretch underwear ($10), or seize a sheer baby doll and g-string set, which pulls double duty as a naughty nightie or as questionable formalwear ($36). Peekaboo panties minimize the use of unnecessary fabric, saving the environment, stale marriages, and the livelihoods of America's lace farmers in one frilly swoop ($8). Conserve cash by perusing the sale section and capturing classic designs for less than $10.
