"Love the whole costume! The boots make it a complete look and she will stand out amongst all the other contestants. The designer struck a too balance between creating something stunning and glamourous but without overpowering @demileighnp. It's incredible," said one fan.
"I’m about to cry. It’s so so beautiful! @demileighnp you’re bringing that title home," said Karishma Ramdev.
Others were not as impressed.
"Is this the actual costume she'll be wearing?" commented someone. "I rate heels instead of boots as well," said Angelique Marais.
Earlier this month Miss SA made changes to Miss SA runner up Adè van Heerden's Ndebele-inspired outfit after major public backlash.
She will be competing in Miss World while Demi-Leigh has opted for the Miss Universe title.
