Fashionable hairstyles like the Victoria Beckham bob eventually get a makeover. Victoria's was monochromatic—pure blonde—but black celebrity Mary J. Blige made it more interesting with multitonal highlights.

It's always a style risk to wear a dramatic haircut with more than one haircolor—it can look like too much is going on—but the Pob, as the famous hair design is called, definitely needed some creative attention.

A multi-tonal version of Victoria's hairstyle like this may be the best look for African American ladies in search of a cool fresh short hairstyle. Victoria herself, incidentally, has changed her bob from blonde to brunette.

If you already have Posh Spice's bob, but want to dress it up a little for prom, or at least change it, you could give it a color makeover.
