Knee-high boots make great sense for fall because they let you get more wear out of everything from skinny jeans to miniskirts.
Tuck in slim trousers for a young look or layer on opaque tights with a skirt or dress to keep out the chill.
Choose a mid-heel height for the most trend-proof look (something 2 inches or less).
Brown boots are a great choice if you wear lots of denim; black pairs with almost everything.
Shop for tall boots.
