Since Saturday Night Live<\/em><\/a> hosts trade one costume for another, fans rarely see the star’s out-of-character looks. Filming pre-show promos, however, allows their true sartorial prowess to shine through. On December 18, this week’s host, Ariana Grande<\/a>, filmed SNL<\/a> <\/em>ads in a vintage Bob Mackie<\/a> gown, originally worn by a fellow Funny Girl.<\/p>\n Luckily for fans, Grande’s archival streak<\/a> didn’t end with Wicked: For Good<\/em><\/a>‘s conclusion in late November. This time, Grande and stylist Law Roach flexed their secondhand sourcing muscles with their oldest non-Wicked<\/em>-related find: a 52-year-old gown from Carol Burnett’s closet. Without Grande’s Instagram post<\/a>, you might’ve though Bob Mackie crafted the halter neckline and column skirt just for her.<\/p>\n An orange, brown, and yellow color story makes its origin impossible to deny: It was quintessentially ’70s. Diagonal chevrons decorated the entire floor-grazing gown, beginning with the criss-cross halter. Roach secured the dress and a matching lemon-colored shawl from Julien’s Auctions<\/a>, a privately-held auction house in Beverly Hills. It scored a spot in the brand’s early December auction, “Bold Luxury: Bob Mackie, Stage Glamour, and The Couture Edit,” alongside Bob Mackie creations worn by Cher, Tina Turner, and more legends.<\/p>\n
