Oti posted an image of the garment on her Instagram account before the show.
Oti wrote under her image: “Happy Saturday hope you enjoy the show!!!!7.05pm @bbcone #greatestdancer.”
Tonight the performers are whittled down even further.
The dancers are tasked with blending styles of dance in the Dance Fusion week.
Contestants stand to win £50,000 and the chance to perform on Strictly Come Dancing.
Next week contestants will progress to the semi-final, so there is all to play for tonight.
There have been concerns that Oti could quit Strictly after her friendship with Kelvin Fletcher generated headlines.
Emmerdale’s Kelvin and the dancer stormed to victory in 2019.
However, there are now fears Oti will resign from the dancing show after being left ‘devastated’ because of reports about her friendship with Kelvin Fletcher.
