Janet Jackson was the guest of honour at the Life Ball 2011, which was held in Vienna, Austria last night.

The singer wore a Marchesa gown from the Fall 2011 collection.

Her ebony duchess satin hand draped asymmetrical gown with a velvet flare skirt appears to nip her in at the waist without the aid of a waistband.

Janet accessorized with a black cuff.

Some dazzling jewels or an onyx embellished clutch were needed to add some sparkle to this look.
