Emily Ratajkowski shared news that she's expecting her first child [1] on Vogue's November digital cover [2], and between the chic, burnt-orange slip dress [3] she's wearing and her vibrant reddish-brown hair colour, she's a picture-perfect vision of fall.

Blame it on my job as a beauty editor or the fact that I have my own hair appointment coming up next week, but it took me a minute to register that Ratajkowski was pregnant when she posted the announcement on Instagram on Oct. 26 because I was too busy thinking to myself, "Wow, her hair looks amazing." Since she's a natural brunette, we're used to seeing Ratajkowski with dark hair, but this auburn-brown shade lately is giving me major fall hair inspiration [4].

This season, many people are spicing up their hair colour with festive tints and highlights to refresh their look. "Spiced gold," "amethyst brown [5]," and "chocolate almond [6]" are just a few of the biggest fall hair-colour trends for brunettes this year, but Ratajkowski's auburn hue might be my favourite of all.
