Plaid prints and tweed fabrics are a match made in fashion heaven, and these two styles look especially fabulous for fall. “Plaid and tweed go beautifully with blue jeans or a skinny pant,” says Sanders. But the key is choosing one color within the plaid pattern (like light pink or blue) and pairing with similar colors, like a pink blouse or blue denim. This will make the outfit fresh and young — not head to-toe drab like an old professor.
