The London 2012 gold medal winner, who has been partnered with Brendan Cole, said that she doesn't normally get the chance to splash on fake tan or feel glamorous, and admitted that the opportunity to dress up every Saturday night is spurring her on in training.
"I love dressing up and feeling glamorous is a whole new thing for me," said Pendleton.
"I just really hope I can stay in the competition - the motivation to get a new dress each week should keep me going!"
Speaking about her naturally pale complexion, she said: "I might get a bit of a tan actually. I don't normally do that sort of thing, I'm quite pale normally, but I feel pretty paranoid stood next to some of these pro dancers. Especially the male ones!"
Pendleton has odds of 15/2 to win this year's Strictly. Fellow Olympian Louis Smith is the current favourite with odds of 9/4.
Strictly returns on Friday, October 5 on BBC One.
