Lingerie for the office! Kourtney Kardashian poses in a black lace bustier to kick off the first work day in 2021

Kourtney Kardashian pulled together a power look of sorts on Monday, the first work day of 2021.

The 41-year-old reality TV sensation was in black business slacks as she posed in the closet inside her Calabasas, California mansion.

But the POOSH founder added a one-strap black lace bustier from Olivier Theyskens to lend a very racy touch.

Kourtney added pointy heels but they could not be seen that well because her slacks were so long.

The single mother to three kids she co-parents with ex Scott Disick had her raven hair groomed but worn down for a serious business meeting look. And the DASH Doll had on minimal makeup but still looked fully glamorous.

The siren has a habit of posing in her closet with her clothing in shoes on display in the background.

In these new images boots could be seen in the shelves with some clothing on her carpeted floor.

The post included two mirror selfies as well as a closeup photo of her delicately sewn lace bustier.

This comes days after she showed off her New Year’s Eve ensemble on Thursday.

The healthy living guru slipped into a plunging patent leather party dress as she toasted to 2021 with ice cold tequila.

Kourtney put on a leggy display as she leaned against a lit up bar donning in the shiny frock, which was styled by the star’s longtime fashion confidante Dani Michelle.

The look was the perfect blend of dominatrix and Barbie Doll chic, flouncing out with flare at the skirt with a body hugging center and plunging neckline.

Making her ensemble all the more edgy, the eldest of the Kardashian/Jenner sisters added a diamond choker and bedazzled Alain Mikli x Alexandre Vauthier sunglasses with heavy 2000s vibes.

Kourtney captioned the trio snaps, ‘Tequila on the rocks with lime,’ referring to one of the famous family’s go-to cocktails.

Little sister Kylie Jenner even started a TikTok trend after declaring her drink of choice during a night out with her sisters on Keeping Up With The Kardashians.

Kylie ordered Don Julio 1942 before singing, ‘Cause I’m gonna get wasted. I just finished a whole cup of 42 and I’m about to go for my second one.’ 

And when none of the brood reacts, she snaps at the eldest of the bunch, saying: ‘Kourtney, what the f*** are you on?’

After the episode aired famous friends Bella Hadid and couple Sophie Turner and Joe Jonas pantomimed the hilarious exchange on Instagram, solidifying the meme’s moment in pop culture history.
