This week the stars have been shunning bold brights and girlie frocks in favour of sleek, structured separates.
Mum-to-be Kim Kardashian kicked off the craze on The Late Show, choosing for an androgynous look, sporting a tux and houndstooth heels. She then reworked the style again in a cape jacket, skinny cigarette pants, high-neck blouse and stilettos to go front row at Paris Couture Week, and now a flurry of fashionistas have followed suit.
Hitting a Sundance Film Festival photo shoot for their latest flick, Very Good Girls, ingenues Dakota Fanning and Elizabeth Olsen played matchy-matchy in mono tailoring. While Lizzie gave an edgy spin in a pleated Chanel blouse and leather trews by her sisters' fashion label, The Row, worn with over-the-knee Stuart Weitzman boots, Dakota's look was a relaxed combo of silk blouse and harem pants.
Over at the Movie 43 premiere in LA, and teen fashion queen, Chloe Moretz, also checked the trend in a lace-tipped tux suit and matching bib blouse. Rosy make-up and bow-detail heels ensured the outfit was young and fresh.
It seems the boy-meets-girl look is firmly back on the fashion menu for our favourite stars.
