I usually never buy stuff over 100, simply because, as a student, I'd rather not go hungry. My most expensive pieces of clothing, however, are over 100 (one particular item is WELL over a 100), but I always manage to have them offered to me for birthdays and christmas and shit.
For example I got a leather jacket this christmas, and being that I have been looking for one that fit for well over a year and a half (apparently I have a weirdly shaped upper body with extra long arms...), and putting money and christmas and birthday 'credit' aside for that single purpose, I could overlook the fact that I would have had to sell a few body parts to pay for it otherwise.
Point being, sometimes, the importance of the price diminishes greatly when said piece of clothing fits perfectly etc etc. Sometimes, it just is worth it
