For special occasions, I wear designer stuff, I have a few Burberry shirts, jackets and a Louis V belt and a Gucci one too. These were all from my own money from working during summer holidays and half term and from my own money (unless they were gifts). I always feel better wearing stuff I have earned, it makes it all that much better. Otherwise for everyday purpose, If it is comfortable, and does not make me look like an idiot then it is fine. For example Levi Jeans, a Zara Jumper, a normal warm waterproof jacket and Air forces or Gazelles does it for me. As a student your priorities are not looking good or "Dripping", it is to work hard and enjoy your young years. Not trying to prove to your mates, "HEY MY DAD IS RICHER THAN YOURS" or "I HAVE MORE MONEY THAN YOU". Don't get caught up in that. Many kids at my old school were and just look like clowns.
