Princess Charlene Enlivens Graduation Gala in Monte Carlo in Sleek Black Dress [PHOTOS]

Princess Charlene of Monaco, who is rarely seen in anything other than a choice of beige, black and monochromatic outfits for official ceremonies, put a surprisingly glamorous foot forward for a graduation event in Monte Carlo.

The Princess slipped on a sleek, black frock, for the event at the International School of Monaco in Monte Carlo, on Tuesday. She teamed her floor-length cropped dress with a pair of black strappy heels and the blonde chopped hairdo gave her an elegant look.

Although she is known for, perhaps, a somewhat monochromatic dress sense, on this occasion the Princess Charlene reflected her glam quotient and, more importantly, this was perhaps a sign the Princess was finally parting from monotone beige coats and daring to sport different style statements. The former South African Olympic swimmer has undergone a fashion makeover in recent months and has been sporting a markedly more glamorous avatar ever since.

The 34 year old princess, who married Monaco's Prince Albert II in July 2011, was first seen in a long, flicked hairdo at the Rose Ball - a traditional annual charity event in aid of the Foundation Princess Grace - in Monte Carlo in March. Princess Charlene wore a strapless black gown with a glimmering gold bodice to the event.

Within a month of the Rose Ball, Princess Charlene began sporting the cropped hairstyle she now favours. Her first public appearance with that style was at the final of the 2012 Monte Carlo Tennis Masters, in April. More recently, Princess Charlene was a head turner at a lunch hosted by the Queen last month, to mark her diamond jubilee. For the event, Princess Charlene wore a baby blue (including stilettos) ensemble.
