It might sound cliché, but if you're feeling a little down about yourself, lingerie could be the answer. Several studies have shown that wearing lingerie can boost a woman's confidence, whether they're in a relationship or not.

When wearing a push-up bra compared to their regular undergarments, women smiled 73 percent more. They also decreased the amount of times they broke eye contact (a low confidence habit) by 41 percent, and they decreased other self-conscious habits like touching their face or wiping their forehead by 64 percent.

Another study from Live Science concluded that wearing lingerie can increase men's interest. It's not surprising, though, because men associate lingerie with sex--and the more enthusiastic he is about wanting you, the more confident you'll feel.
