Black slacks, a plaid button up shirt, scuffed brown dressy looking Merrells. No jewelry. This is what I wear pretty much every day I go to work. Some days its a light sweater (purple, brown, or gray) or a slightly different patterned plaid shirt.
I dress because others expect me to look somewhat professional. If it was my choice I would wear pajamas everywhere. As soon as I get home from work I throw on the PJs. I'm all about comfort, and severely lacking in style!
