During menstruation, panties and intimate wear may get stained with blood. In this case, period underwear is the best thing to opt for. Designed like any regular panties, they are generally in a hipster style to accommodate the pad. Usually, they are in a darker shade and come with a pad holder. You can easily align your pad in the crotch area, secure it, and wear the underpants as you would normally. Some options and varieties also feature an absorbent and changeable crotch area in case of any leakage.
