I wear what ever I feel comfortable wearing and that it's clean too, it's different day to day.
The only day I wear something specific usually has to do with a certain personal event. For example I wear my Pokemon t-shirt when ever a specific Pokemon episode I like premiers. I wear a specific football jersey when that team plays.
Pants and shoes I don't care for color or brand, I just wear them if its clean and cheap in price at the store.
T-shirts are important to me, I wear something that represents something I like. Music t-shirts, movie t-shirsts, TV show t-shirts, and sports jerseys.
to answer a few suggested questions:
What is in your wardrobe? Do you have a lot of clothes or not? - I have tons of t-shirts from various bands, movies, and tv shows I like. At times its tough choice deciding what to wear.
Do you have a particular fashion style? - Rock N' Roll style some days, other days I'm a sports fan.... depends on the day or events
Do you have any favourite brands? - I never pay attention to brands. As long as the shirt has the design I want I'll buy it - rest of the clothes (pants, socks, shorts - I don't wear underware) I'll get what ever is available or on sale, so again brands don't matter
What are some of the more outrageous things you have in your wardrobe? - probably some t-shirts with extremely graphic designs, such as some of my Deicide (a shirt that reprents the Scars of the Crucifix album) and Cannibal Corpse (with the Butchered at Birth album cover) t-shirts.
