The 65-year-old star - who was formerly known as Bruce Jenner before her gender transition - has admitted she was wearing a corset under her dress at the awards, which she attended to collect the Arthur Ashe Courage Award, and the restrictive clothing did put a strain on her body.

Caitlyn said: "Getting glamorous for the ESPYs was a big process to go through, but it was amazing and so much fun. I really wanted to feel real comfortable up there (although there was a corset under that dress, so I don't know how comfortable I was!). I wanted to feel good. I wanted to feel pretty. I wanted to be myself."

Caitlyn also confessed she was very "worried" about what to wear to the event, but when Donatella Versace approached her about designing a dress for her, it was a dream come true.

In her latest blog post on CaitlynJenner.com, she said: "Over the last month, I was so worried about what to wear. Donatella Versace reached out to me and said, 'I want to do the dress.' I said, 'I am SO in.'

"We started with designs; they made the dress in Italy. Her head dressmaker came over and we did two fittings to make sure we got it just absolutely perfect. It was like every fantasy of my life come true. (sic)"
