Vintage plaid grunge preppy style bell bottom pants

RR brand vintage plaid bell bottom pants. No interior tags to say contents of fabric, I would guess a poly cotton blend, feels like heavy twill. Like new for vintage. Inseam 31.5, waist 15.5 hips 19, bell bottom 11. I'm a size 4 or 27 in jeans and these are one size larger than perfect for me. Very rare and amazing vintage item.
