Certain fabrics epitomize different seasons. Tweed is winter, pastels are spring, seersucker is summer and plaid is fall. When I think of plaid, I often associate it with school girl uniforms and preppy yuppies. These two looks below offer a mix of conservatism and sexiness -- a style, I have to admit, fits me to a "T."
