For me, I prefer to wear clothes that feel good. I'm not too picky (I do like to have a wide variety of colors in my closet though I do have a lot of blues). I just sort of do my own thing.
I tend to wear denim pants nearly everyday, and I'm not big into skirts or dresses. I have a few, and I do think it's good to dress up every once in awhile, but I honestly don't like the feeling of openness that skirts and dresses leave between my legs.
I also don't wear turtlenecks due to a life long hatred of having objects closely positioned around my collarbone/neck area. Necklaces and scarfs, interestingly enough, don't bother me, but nearly everything else does.
I also dislike wearing anything too tight, low cut, or sleeveless. This is mostly due to discomfort and the paranoia I have regarding disasterous wardrobe malfunctions in public regarding these types of outfits. If I feel like I could potentially be exposed in a way I don't want to be seen, I'm not going to want to wear a piece of clothing.
