Primer Magazine, a relatively good guide with lots of style and life advice for clueless guys straight out of college (sort of eases you into it), has gotten custom suit maker Indochino to give out a coupon to readers. You'll get 10% off any of their suits, a free dress shirt, and free shipping. Indochino already has department-store prices for their suits (which, if they're even a little bit from perfect, they'll pay for you to take to your own tailor to fix).
Not an advertisement, just thought I'd let you guys know. I have to save for stupid college instead of buying the one I'm most interested in (the light gray three-piece). You should veer away from the lowest-priced suits, though: almost all of them are 100% polyester.
