There are plenty of nude sculptures at the National Gallery's summer blockbuster exhibition Hyper Real, but there is going to be even more nudity in January.
The gallery is holding a one-off event on January 13, for 100 people to enjoy the art in their birthday suit.
On the night, participants will gather and disrobe together in the gallery's foyer, and everyone gets a cocktail to ease any nerves.
Participants must be over 18, and they won't be completely in the nude - everyone must keep their shoes on, presumably for safety reasons.
Unfortunately you can't buy tickets for the session - you can only win your way in, with 100 tickets up for grabs.
And wallflowers need not apply - the event is being used to create a curated photograph and video inside the exhibition, although full frontal nudity won't be used.
After the tour, the group will get dressed and bussed over to Nishi Gallery in New Acton for the after party, where clothing is also optional.
This will be the second time naked events have run at the gallery, and in April 2015, two groups were led through the James Turrell: A Retrospective exhibition.
Those tours were led by Melbourne-based artist Stuart Ringholt, who had previously held other nude gallery tours at the Museum of Contemporary Art in Sydney and MONA in Tasmania.
