Cheryl Cole was seen leaving her hotel in Paris, France on Thursday (June 14).

She picked to wear a light blue, olive, black, and leopard colorblock mini dress by Ksubi.

Her fitted dress with a zipper down the center was matched with leopard and light blue platform pumps by Charlotte Olympia and a gold bracelet.

Cheryl's heels, however, are an awkward choice for her dress as the additional leopard is distracting.
