Gossip Girl star Chace Crawford is donning neutral toned casual wear because…

A) Photographer Mikael Jansson just shot the babe for a upcoming Fall ‘08 Gap ad campaign.

B) Castmate and rumor girlfriend Blake Lively made him swap his ripped denim pants for chinos because she thought his personal style was lacking substance.

C) GQ magazine asked the Texan to strike a pose in their spread called The Perfect Tan, which teaches men how to pick summer outfits that will compliment their new glow.

Now, no cheating.
