These past couple of years tights have really become important in fashion and can make or break an outfit. Changing the color of your tights can make you look more current. This outfit stands out in part because of the fusia opaque tights.
Dark tights will make your legs look thinner. Light tights are hard to carry off as they will add weight. Patterned tights can make you legs look larger. Generally speaking a large pattern will make your legs look larger and smaller patterns are easier to wear. Polk-a-dots are fun and look cute but don't go with too large of a polk-a-dot as it can look clownish. Textured or ribbed tights can be sexy and add some richness and warmth to an outfit.
