It seems sheer chic is Jessie J's latest thang as the singer chose not one but two see-through looks for the Oxford Street Christmas lights ceremony.
Jessie arrived and posed for pics in a cool pair of bright red Preen trousers teamed with a black sheer top, under which she chose to wear a nude-hued bra.
She then slipped into a black halterneck dress that consisted of a bodysuit and a long, completely transparent skirt for her performance of Price Tag and Thunder on the Selfridges roof canopy.
Jessie was joined at the ceremony by James Arthur, Conor Maynard, Lisa Snowdon and Dave Berry, and crowds lined the streets to check out the concert and the pretty scene.
Talking of the experience, the singer told the Daily Mail: : "I always used to make my parents bring me to Oxford Street to see the Christmas lights so it's an honour to actually be switching them on this year.
"I spend a lot of time shopping on Oxford Street and this year will be no different. The lights switch-on is a prestigious part of the festive season for Londoners and I'm proud to be a part of it."
