The gown, which was designed by Biji Gibbs, is made from black velvet material with a simple sihoutte.
A standout feature is the beaded sleeve, which Keyi says was inspired by her Xhosa heritage.
“Honestly, It was just capturing who I am as a person, because I’m very grounded in who I am, so I don’t want to go present myself in front of the world, showing something that is less than who I am,” she told The Juice at her Miss World send-off.
The Miss World pageant takes place on 8 December in Sanya, China.
The Miss World delegates had a press conference on Wednesday, and Keyi was one of the 12 chosen to speak at the conference. Keyi was later chosen as one of three contestants to conduct press interviews alongside Miss Canada and Miss China.
