it all depends on heat/humidity/where i am going.
1 thing however, i absolutely hate wearing formalwear even though people say i look good in a suit and s**t.
but normal everyday outfits....
Warmer weather (considering i think mid 30s is warm): shorts (i wont wear jean/denim shorts unless its the last thing clean i own), t-shirt (down to wearing whites/blacks/more neutral tones), muscleshirts with an open button-up over it (if i am usually going out for the night).
Cooler weather: just replace the shorts with a pair of jeans or cargo pants, usually either silvertabs or similar. Sometimes a zip-up hoodie on occasion.
This has changed quite a bit from my days of wearing a hoodie even in 90 degree weather. Back in school i used to be the person youd see with chains and whatnot all over thier pants, pins on thier hoodies (still love my stewie griffin one as well as the evil monkey, both from family guy. T-shirt wise, i still wear alot of band shirts, normally iron maiden stuff (get ALOT of complements if i wear pretty much any iron maiden shirt, especially some of my slim-fit ones.) Wear quite a bit in the way of Quicksilver/etnies/DC/zoo york, so yeah. One rule, the darker coloured shirts, i am more likely to go for a slim fitted one.
