Cotton ones that I get from Walmart. I don't ever wear my Victoria's near or on my period.

Men's boxer briefs if your like me and bleed heavily and need the gigantic super maxi pads but women's underwear doesn't have enough room. Bonus to men's underwear, theyre comfy and don't ride up your butt 😂😂

my mom has bought me some undies that are plain and cheap that i sometimes wear. honestly though, i still wear somewhat nicer ones a lot, like kind of oldish, plain victorias secret undies, i dont care. i dont usually have overflow plus it usually washes out fine if i do. at the end of the day, its just underwear and its all replaceable
