Most important fashion tips:
If you're going to spend money, SPEND ON A WATCH, SHOES AND A HAT aka things you wear all the time, THUS YOU GET THE BEST BANG FOR BUCK!
The important thing is NOT name brand, it's FIT and colors that work well with your skin tone and body type
Also make sure you take care of your body, no you don't need to be "jacked," but don't be a sloppy oaf. Being 14-16% bodyfat (for men, women it's obv higher) with muscle mass is impressive to the average person and incredibly easy to maintain, so take care of yourself as well, you want to talk about wearing things 24/7? Try looking up this thing called your "body" apparently you can't get rid of it!
Finally, make sure you have GOOD POSTURE, there is nothing worse than seeing a good looking or even fit person with a hunched back or severe posture issues, especially in the day and age when you can correct that shit in a few weeks
