Charlene, Mary and Letizia: this week's royal style

It's been a bumper week for royal style watchers as Princess Charlene, Princess Mary, Princess Letizia and Zara Phillips all stepped out at high profile engagements.

On Monday Charlene wowed onlookers in a strapless white jumpsuit and matching belt at a private film screening and two days later the Monégasque royal channeled Hollywood glamour in a dramatic olive green halter-neck dress at the Princess Grace Awards in New York.

Pregnant Zara Phillips dressed her baby bump in a lack floor-length gown on Thursday, accesorising her look with diamond studs and a mulberry clutch while Spain's Princess Letizia reflected her love of rock music in a chic yet edgy outfit of leather trousers and scarlet heels.
