Kylie and Kendall Jenner show support for Dad Caitlyn Jenner at ESPYS

I really got confused there for a second,wasn't sure if i should say the girls supported their father or their mum..sighs..but the in the end i settled for dad..it's confusing right? I can talk about Caitlyn and caller her a woman no problem,but when i talk about the kids,do i call Caitlyn their mum or dad? It is confusing..but moving on..
19 year old Kendall and her 17 year old sister Kylie attended the ESPYS to support their Dad, Caitlyn Jenner. Kendall stepped out in a black gown by designer Alexander Vauthier with sheer see-through panels, a plunging bra style neckline with her décolletage covered in a fine chiffon while Kylie stepped out in gold glittering sequin gown.
