If you're suffering from bacne, chest-ne (yes, chest acne) and breakouts on the tops of your shoulders, it may be time to toss your favorite bra. You want a snug fit for support, but if your bra is too tight, it can trap sweat and bacteria that clog the pores and hair follicles on your chest.

According to lingerie experts, we should be washing our bras in cold water (to retain the power of the elastic) after three or four wears. Don't rely on one or two bras -- have a good six to seven that you can rotate through so you're doing laundry less often. When shopping for new bras, look for breathable materials like cotton to reduce sweat buildup and get fitted by a pro to make sure you're purchasing and wearing the proper size.

You know how sweaty, oily bangs give you those annoying little breakouts along your hairline? In the summertime, your long hair plays the same game. The styling products and oil in your hair sit on your chest, back and shoulders all day long, clogging pores and encouraging breakouts. Try a pretty updo to keep cool and to get rid of back acne.
