In this case, the outfit was a bikini with knee-high boots under lots of fringe.

"I'm in boho-psychedelic," Prinsloo said. "It's very Coachella. It's very psychedelic."

Underneath all the glitz and glamour, fans will be happy to know that Victoria's Secret Angels are still very much human, as we found out.

"I'm going to solve my problem with my sweaty feet this year," Prinsloo said, giggling. "I sweat when I'm excited."

Prinsloo is a veteran of the annual fashion show, joining fellow returning Angels Adriana Lima, Alessandra Ambrosio, Candice Swanepoel and Lily Aldridge.

In addition to the returning favorites, the catwalk will also feature some new faces, perhaps most notably, rising up-and-comer Kendall Jenner.

"I would just say, have fun," Prinsloo said, giving advice to the 20-year-old reality star. "It's such a fun show. We all have so much fun backstage. We have fun after the show. We have fun at the fittings. It's just kind of a great family to be part of."

The 2015 Victoria's Secret show will be taped on Nov. 10 in New York City and air on CBS Tuesday, Dec. 8. Click here for the full list of models.
