Ok, my wife brings me with her when she goes clothes shopping and she doesn't have to drag me cuz for some reason I know style and she likes a man's eye. Well kinda... she says I'm 1/4 gay... I can pick an outfit, I can match wall colors to trim and carpet, I'm just not into the whole boofing a guy thing.
SO, an easy way to clean up and look good is first and foremost a pair of black stretch pants flared. You can wear any comfortable shoe, from a boot to sandals, with any height heel. For top... there are plenty of flattering things that are form fitting but not uncomfortable. If you're self conscious about your waistline, wear something with a busy pattern or something that kinda hour-glasses under the bra but is flowy in the middle. If your hair isn't specatcular, pull it back in a ponytail, but a high ponytail... show off that neck! And a light perfume or shampoo wouldn't hurt. Maybe Heavenly by Victoria Secret, or Herbal Escense.
Some good stores: Forever 21, Kohls, Mervyns... more expensive Macys, Nordstromes...
Ok, now that THAT'S over with, I'm going to go drink a beer and start up my chainsaw cuz I have a falling tree in my backyard that needs cutting down... and I need to go buy some lumber cuz I need to rebuild our fence. Where's my hammer...
