While the main purpose of the renowned Victoria’s Secret Fashion show is to promote lingerie and clothing, it’s no secret that many viewers are more interested in what’s underneath the apparel. As usual, at Monday’s 2016 rendition of the show, glamorous, deep tans were a prominent part of the signature look of the Victoria’s Secret “Angels,” who seem to fascinate women even more than men.

Along with insane fitness routines and the work of a small army of hair stylists and manicurists, developing a sensational tan is a pillar of show preparations for the world-famous supermodels. A number of sources have reported that it took three liters of spray solution in total to get all 51 models to the desired shade.

While spray is used to help the models attain the perfect color, it does seem that some of the Angels sport more natural tans. “For me, it’s really about having a nice tan. If you have a nice tan, it looks really nice on the runway,” Brazilian supermodel Alessandra Ambrosio told website POPSUGAR before the 2014 show. “I was just in St. Barts with my kids, and it was nice to get a little tan and do some outdoor exercises, like walking, running on the beach, and swimming […],” she says.

When asked if spray tanning was also part of her pre-show repertoire, Ambrosio told POPSUGAR she “might apply some tanner,” gesturing at her legs.

Whether the models’ looks are au naturel or via spray tan, the VS Show is always a great showcase for the enduring beauty and popularity of a tan.
