Long sleve plaid shirt.. help! (hair too)?

Wear a forest green or orange camisole underneath. You could try a scarf out with it, but I'm not sure if that would work with it. If you tuck it in, wear a cute belt (black or brown). Don't add any different colors to the outfit because the shirt already has so many. Stick with those. Don't wear cowboy boots with it, it would make it look more like a cowgirl halloween costume. I would wear black flats or black (or brown) suede boots that go a little below your knee. As for your hair, leave it straight down. If you want, tease it a bit. Hope this helps. :)
