Plaid returns almost every fall. It's no exception this fall, when red is the it color. Why not pick a red plaid print then?
Red plaid is more flattering than solid red in a number of ways. First, plaid divides the horizontal view and can therefore optically trim your body. Secondly, solid red may make your lips look not red enough by contrast, but red plaid won't have that undesired effect. Thirdly, plaid is preppy, and preppy equals youthful.
The list can go on. I'll just stop here. Happy shopping!
