Jennifer Lopez couldn't decide whether to wear trousers or a dress to the Atelier Versace fashion show on Sunday - so she just wore both.

The star dazzled in a strapless floor-length white gown with a hip-high split. Yet instead of flashing the flesh, she donned one sparkling trouser leg, successfully adding another dimension to the unique gown.

It was a statement look for the 44-year-old and showed off her curvaceous figure to great effect.

The strapless frock included metal belt buckle detail on one hip and a pocket on the other which the singer, 44, made full use of when she posed for pictures including one with designer Donatella Versace.

She donned strappy stiletto heels which matched the pearlised tone of her gown and accessorised with gold jewelry.

Close friend Donatella Versace wore a black suit and left her blonde tresses down and straight in her typical style and wore a large pair of hooped earrings.

They posed together on the steps of the Paris Chamber of Commerce and Industry near the Champs-Elysees where the show was held.

Donatella kicked off six days of haute couture catwalk shows in Paris.

The Italian designer sent out opulent blue fur coats, voluminous silk ball gowns and gold-buckled corsets in what she called a celebration of "construction and deconstruction".

In a string of a asymmetrical looks, jackets and trousers were cut away to one side while one skirt was slashed so high it revealed the model's hip.

Plunging fronts and backs had thin strips of vinyl embroidered on transparent fabric to create graphic shapes. – Daily Mail/Sapa-AFP.
