If you don't open your closet every morning to see at least one pair of sexy, knee-high boots that can be worn with jeans, a suit or a skirt, it's time to invest. Choose a nice leather pair in black or brown with a moderate heel between one and two inches high. Avoid any extremes when it comes to round, pointed or square toes, going for something that will work well regardless of current trends. Just make sure that you absolutely love whatever boot you purchase - you're going to walk a lot of miles in those heels.
