1) How much are you trying to raise? What if it fails to meet the goal?
2) How exactly can I get a perfectly fitting shirt? What do I need/get to measure (i.e. is it two things and you get close or is it more)?
Love this idea for a company, by the way. I often have to find clothing in odd corners to fit my physique (tall, thin, long arms and torso). I've ordered tech shirts just because of how they fit (e.g. http://www.googlestore.com/Google+Redesign/Wearables/Men+s+T...) and buy lots of cycling oriented clothing as it seems to fit me better than "mainstream" clothing without being tailored.
