Andreea Bogdan, after Balmain, Paris, October 2015. 
A lovely way to accessorise a classic white shirt and boyfriend jeans: add a vintage scarf + slingbacks. 
Recreate Andreea's look (kind of):
Boyfriend jeans — Frame Le Original jeans, MiH Jeans Linda high-rise boyfriend jeans, Frame Le Garcon jeans, Whistles Boyfriend jeans, Golden Goose Deluxe brand Kim boyfriend jeans, or Current/Elliott The Boyfriend jeans
Slingback pumps — Jimmy Choo Tide pumps, Clarks slingback kitten heel pumps, Christian Louboutin Apostrophy slingback pumps, Miu Miu Patent leather slingback pumps, Erdem Aerin leather slingback pumps, Tabitha Simmons Lily leather pumps,  Fendi Bag Bug embellished leather pumps, or Valentino Rockstud caged pumps
