From drinking blood to dressing like a vampire.

Megan Fox dazzled in a dark and daring look from Mugler at the launch of the fashion house’s collaboration with Jimmy Choo in LA Tuesday night.

And the following day, the actress shared the inspiration behind her outfit, comprised of a sheer corset top ($3,019) styled with a miniskirt ($1,023), seamed tights ($161) and strappy heels ($1,175) from the new partnership.

“It’s giving Dracula’s maid,” Fox, 35, captioned shots of herself striking suggestive poses in the all-black ensemble.

Her engagement ring from fiancé Machine Gun Kelly — a unique two-stone sparkler featuring both of their birthstones along with literal thorns — was also on full display in the social media snaps.

Joining the “Transformers” star at the Mugler and Jimmy Choo bash were Kardashian BFFs Stassie Karanikolaou and Stephanie Shepherd, influencers Olivia Jade and Dixie D’Amelio, songstresses Chloe Bailey and Anitta, actress and newly minted makeup mogul Peyton List and “Call Her Daddy” podcaster Alex Cooper, among others.

Almost all guests sported head-to-toe Mugler for the fashionable fête, where Belvedere Vodka cocktails were served.

Fox has worn Mugler numerous times over the course of her recent style ascent, memorably rocking a barely-there LBD to the 2021 Billboard Music Awards and a see-through nude number to that year’s VMAs.

We’re guessing MGK — who urged his lady love to wear the latter look — is a Mugler fan, too.
