I was an attorney before I started this company, so I can't stand this part, but it's necessary because I've learned during the course of my career that people are greedy, ignorant assholes.  Here you go: 

If you have a problem, email us.  We'll fix it.  If you hate whatever it is we've sent to you, email us and we'll get it fixed or give you a refund.  Whatever you want.  I don't care.  If something doesn't fit, let's get you into the right size.  This is supposed to be a fun experience.  We will make every effort to put a smile on your face. Seriously, it's t-shirts dude.  Chill the f-out.
