The Solution is Garment Guard: disposable adhesive underarm shields.
Garment Guard is the original disposable underarm shield and simply the best armpit pad on the market. These premium, super soft, 100% cotton stickers adhere to the inside of clothing, preventing embarrassing wet marks and yellow perspiration stains on whites and helping your clothing investments (and old favorites) last longer. Slap a couple of these on your shirt before you head out, and rest assured that these sweat pads soak up wetness and keep it from showing on your blouse. As an added bonus, you won't have to do laundry as often or spend as much money on dry cleaning. Garment Guard can also be a great natural alternative to turbo-powered chemical antiperspirants that can have negative impacts on your health.
