Girls! Period underwear! Seriously!
I seen a lot of what underwear posts and my answer is always Period underwear.
The crotch lining is a bit broader to everything can fit in nicely
The lining is made out of a thicker material and is sturdy enough to tuck somewhat well. I feel comfortable wearing most things that aren't skintight.
They just look like normal feminine underwear
They are simply comfy as fuck
You can usually find them with the feminine hygiene products.
