“Underarm shields are well-made and beautifully constructed. Unlike other products on the market, they are cut low in back and front and along the side of the collar so they don't peak through the overgarment.”

“I got this shirt because I use natural deodorants and they don't work as well as antiperspirants. This shirt protects my blouse and keeps me odor free.”
