Television personality Caitlyn Jenner made an appearance at the 2015 ESPY Awards, and she looked absolutely stunning.

The former Olympian accepted the Arthur Ashe Courage Award, thanking her family for their support.

"I always wanted my children to be so proud of their dad, for what he was able to accomplish in his life. You guys have given so much back to me - you've given me so much support." Jenner said during her acceptance speech.

"I'm so grateful to have all of you in my life. Thank you."

The 65-year-old looked elegant in a long white wrap dress at the event.

Jenner - formerly known as Bruce - underwent a gender transition earlier this year and is now set to star in her own reality TV show, I Am Cait.
