But don't worry, Binks hasn't taken the plunge and reached for the bleach - her glamorous 1950s-inspired look was actually for a photoshoot.
The Made In Chelsea star posted a picture of her makeover on Twitter along with the caption: "Guess who! ;)"
Binky is seen with pale blonde locks swept back into a bun while wearing a headscarf printed with little cats.
Her make-up is pretty dramatic too, with thick liner adorning her upper lashlines, plus super-sized false lashes which added a flirty flutter.
The starlet also flaunted flawless skin with sculpted cheeks, plus a slick of lippy and bold brows.
It's certainly a far cry from her usual minimal Chelsea look, but it seems Binky's image overhaul was a hit on the Twittersphere!
One fan commented: "you look like a vintage vixen." Meanwhile, another said: "stunning!!! Classic beauty!"
We have to agree - Binky did look pretty fab with her retro hair and make-up. We wonder if she'll be rocking the look on Made In Chelsea anytime soon?!
