Fashion for Nerds

The new Fashion4Nerds.com simplifies male fashion so that even engineers like me can understand how to dress ourselves.  It's like Fashion for Dummies, except dummies understand fashion better than nerds, which makes sense since fashion is hardly logical.  I'm sure O would love for me to memorize the whole site.

Unfortunately, it doesn't give advice on how to ask a stylist for a good haircut.  I've never figured out a way that always works.  Ladies?
