I prefer a more relaxed straight leg fit. I cringe when I see teenager or even worse, grown men, wearing skin tight jeans. I think they look awful and I wonder how they get into their jeans in the first place. I think the classic straight fit is more manly and that's what I go for. Skin tight jeans are for girls, in my opinion.
I prefer skinny bottoms because they fit me nicely and make my legs look nice. I find that bell bottoms make me look fatter than what I actually am. They also go great with flats, slippers and can fit easily into boots. I wouldn't purchase ones that have strange colours and patterns on them though; I'll stick with a navy blue or a black pair.
