Red may be a classic nail polish shade, but as Katie Holmes proved during her appearance on The Tonight Show yesterday evening, gold is a pretty decent alternative. Not only can the metallic wear as a neutral, but because of its lustrous finish, it instantly dresses up the nails. It's also versatile enough to go with an urban style of skinny jeans and fringed boots to something a bit more elegant, like a cocktail dress. You can even use different textures and hues of the color to create two trendy styles: the ombré manicure or the one-nail-painted-a-different-shade look.
