Dick & Dom may have to reuse these costumes for Saturday Night Fever.
Dick and Dom and Jo Brand will be dancing with Dragon's Den judges and former Blue Peter presenters in a special series for Comic Relief.
They are the first wave of competitors confirmed for Let's Dance, where celebrities must recreate classic routines from films and pop videos.
Comedians Robert Webb, Paddy McGuinness and Leigh Francis, in the guise of Keith Lemon, are also on board.
Anton du Beke will be the chief judge when the show starts in late February.
He will be joined each week by two guest judges. The judging panel and viewers will vote for their favourite dancers each week to go forward to a final dance off on Red Nose Day weekend.
Three heats will produce six acts for the final but contestants for the second and third heats are yet to be announced.
A team of choreographers and stylists will help the celebrities to recreate iconic dances from Thriller through to High School Musical.
The competitors will be a mix of solo dancers, duos and groups.
Blue Peter is fielding a team of eight ex-presenters including Anthea Turner and Peter Purves.
Dragon's Den meanwhile is offering Peter Jones, Duncan Bannatyne and Deborah Meaden up to the dance floor.
Claudia Winkleman and Steve Jones have already been confirmed as presenters for the BBC One show.
