Hows about just wear what the hell you want. Style is individual if you think you look cool then so be it. After all your clothes will get wrecked anyway so there isn’t really any need to buy the latest gear.
If you fancy wearing a plain t shirt and shorts that’s fine. If you fancy wearing lycra then that’s entirely up to you. Personally I just put stuff on thats comfortable and relatively hard wearing. Graphic Design and IQ has nothing to do with anything.
I’m sorry but you have lined yourself up for all these comments. Hook, line and sinker. Just wear what you want.
