Unless the denim is cut loose I am not really a huge fan of wearing pants. I think part of the reason is I've successfully managed to gain an excess amount of weight which I can't shake regardless of how much I exercise. I think I am destined for a life of gluttony and while I don't really like being heavier I am quite lazy and I cbf getting rid of it.
Whatevs I've improvised anyway and have turned to tights as pants instead of wearing real pants and the beauty of this is that it holds you in without feeling too tight (god bless lycra) and given the different styles of tights available you really can't go wrong.
I'm a fan of the shiny tights. It makes me feel like I'm dressing up even when I've only got shiny lycra on. YEAH! it's so good for casual wear as well as night wear. See below

I think I have a thing for black.
