Ha! I don't have to worry about it anymore, getting plenty. But I was too skinny for awhile (stress, I get stress anorexia basically, better now) and had these flared stretch jeans and I swear to God every time I wore them to a shop, whoever was standing behind me in line would try to chat me up. They must have been the most flattering pants on the face of the earth for skinny chicks.
Yeah it's like they almost built curves where I didn't have them, always have had an ass with some shape - I work out, lol - but not tight waist at any weight (kids, but also just build, no vertical room between ribcage and hipbones) that flare on skinny legs and slim hips is so, so flattering but ends up looking too exaggerated if you are legit curvy.
