Daily Mail on top form

From The Daily Mail:

... Yasmin Le Bon's love of the unusual left her red-faced on Monday night, as her black dress turned sheer under the photographers' bulbs when she was photographed at the VIP Chanel party in Mayfair...

Instead, Yasmin's breasts could clearly be seen through the thin fabric of the gown, with the mother-of-three appearing either unaware or unconcerned about the fashion faux pas.

So which is correct? "Red-faced" or "either unaware or unconcerned"?

Going by the accompanying pictures, I'd assume the latter.
