Skinny jeans are really done, especially with chucks. The train has left the station with skinnies.
Yoga pants - you mean like form fitting cotton spandex? Not the PINK on the butt ones. If you've got the legs, then by all means, although combining them with Uggs is yet another era that has come and gone.
Yoga pants all the way! My bigger pet peeve is if the girl acts like a bitch or not. If she plays games and acts bitchy then it don't matter what she is wearing because I don't want her. Treat a guy well by being sweet and it really won't matter what you wear.
