I'm trying to replace 2 pairs of denim - a white pair of jeans and a medium wash relaxed skinny. I also recently bought a pair of Pilcro slim bootcuts. I made the mistake of thinking they would have a slimmer leg opening but were slimmer in the thigh instead.

My question is what are the most flattering leg openings for different styles of jeans? The 18-inch Pilcro bootcuts seem too wide to me now and my white boyfriends don't seem to taper enough to be flattering when rolled. Can I have a primer on the best size of leg opening for different denim styles? Is this universal?
