For about 20 years (before that I couldn't dress myself) I had very particular tastes in clothing. It cannot be itchy, like wool, or some fake materials. If it's going to be worn during the winter, the material has to be incredible soft so I can sweat in it, and not get itchy. I remove all the tags of my clothes - pants, shirts, shoes if necessary, underwear and bras. I used to dress in monotone - I remember in particular having a magenta outfit in 4th grade. When I was in 3rd grade, I started picking all the embroidered logos off my clothes. All my clothes are plain colors, with no designs.
About two months ago, I started working and was able to go clothes shopping. I spent about two months prior to shopping really just examining what other people were wearing. I looked for key colors - green and brown being my favorite - and looked to see what others considered a "complete outfit". I was a bit surprised, but then one day I went on a spree at Good Will. I now wear only soft, stretchy pants (gaucho and palazzo) with a longer t-shirt and a long, mid thigh length cardigan, or hoodie. The colors I wear are brown, black, white, and green. I wear red on occasion. I have very few other colors. I tend to wear certain "outfits" quite often, and have been known to wear the same thing two to three days in a row because I liked it so much. There is one pair of pants I absolutely love wearing. They feel so good! They're cotton and (something stretchy) palazzo pants that I had to sew a little tighter because they were too big. They fit so amazing well, and I think the back looks neat (where I sewed it). I wear underwear only on my period. Other than that, I do not wear them.
At home, when no one's around, I do walk around naked most of the time. I like wrapping myself in these really amazingly comfortable sheets (with the tags removed, of course).
