There are a few great hairstyles for NW2-3's...
THE CLOONEY (circa From Dusk Til Dawn)
Sorta like a caesar. Cropped short, same length all over and brushed messily forward to cover some of the receding parts. Great if your recession is a little more advanced. Not a straight fringe line like the caesar, so there is a natural shape to the front.
THE WILL ARNETT (from Arrested Development)
For guys that like a bit of length to their hair, grow it out and brush it back. Don't even try to conceal the recession. Works well if you're a NW3, but with hair still relatively thick in the non-receding parts. This is also the Jack Nicholson and Christian Slater, I guess.
THE EDWARD NORTON (from Fight Club)
The good old-fashioned side-part. The side-part has made a huge comeback recently and a lot of male models sport it too. If your frontal density is reasonably dense, then you can get away with covering your recession very well. Come close to a caesar, but follows more of a sloped angle. You can do a lot more with the fringe too, like brushing it up a little or keeping it slightly messy. Works better with a NW2 than an NW3 though.
THE JUDE LAW (from everything he's been in)
Grow it out, mess it up and sweep it forward. Works better with reasonable density of course, and helps if your recession has taken more of a V shape.
