First things first: body odor isn’t caused by sweat itself, but actually by sweat mingling with the naturally occurring bacteria on your skin. To that end, Truly’s uses sugar (which was used pre-antibiotics to prevent infection), baking soda (which prevents itchiness and absorbs icky smells), and coconut oil (which packs a one-two antimicrobial and antifungal punch) to annihilate bacteria.
As for the stuff itself, it smells and looks a bit like cake frosting — in a good way. Because of the coconut-oil base, it melts into a liquidy consistency between your fingers and absorbs invisibly, sans sticky residue. In other words, your LBDs are safe.
