I have a hell of a time fitting into most normal stuff (MUCH worse for organic or hemp shirts), and combined with my past bad experiences with so many of the "high quality" organic and fair-trade items that fell apart on me after a few wears, I pretty much gave up on a lot of it. Now I just buy things that fit well, are comfortable, and appear to be capable of lasting me a good run before wearing out. Too many of the pricey items that are supposed to be of exceptional quality for fair-trade/organic clothing are comparable to the quality you get at Old Navy - sure, it may look okay when you first buy it, but if it survives one season and is still wearable, you're ahead of the curve.
I used to do all I could to buy more such things, but when you pay $30+ for a t-shirt and it's worthless after 4 washings, you get pretty soured on it. It isn't really helping the planet any if you have to spend more for something that falls apart quickly and needs to be replaced, so in the end, I realized that having to discard/donate half my wardrobe every season was more detrimental to the environment than getting something that lasts
Ok, so the "fitting into normal stuff" isn't nearly so much of an issue for me
, but I'm with you regarding buying stuff that lasts. I had the greatest, most comfortable organic bamboo shirt...until I wore a hole in the shoulder (???) 3 months into owning it. Bamboo may be a renewable resource, but the $40 it cost isn't
