“Bridgerton” stans are serving looks — Period!

Fashion-forward fans of Netflix’s most popular passion-fueled period piece are slaying trendy throwback 1800s styles. 

Taking its throne on TikTok as an elegant timeline-filler, “Regencycore,” or “royalty core,” gives a reboot to romantic high-society vogue of the Regency era. 

With the girls dripping in lace and pearls a la Daphne Bridgerton, and the gentlemen giving godly Duke of Hastings vibes in billowing-sleeve shirts and velvet blazers, it’s a trend that would make modiste Madame Delacroix proud. 

Influencer Caroline Calloway — the so-called Instagram scammer of 2019 — joined in on the fashionably fancy fun, too. Channeling her inner-Daphne, Calloway, 29, got naughty ladylike for subscribers to her OnlyFans channel.

With a viewership of over 63 million, the “Bridgerton” effect on the fashion world has caused a surge in cyber searches for empire-line dresses, lacy corsets, ivory satin opera gloves and bedazzled headpieces, according to global fashion-info engine Lyst.

So break out your best “Bridgerton blue” ballgown, and button up that embellished brocade vest, honey. 

Unless, of course, you’re prepared to have Lady Whistledown pitilessly tear you down all season for your peasant apparel. 

Speaking of the gossiping devil: Lady Whistledown took to Instagram Thursday, announcing the long-awaited second season of “Bridgerton” via her infamous “Society Papers.”
