Kylie, 24, was anything but buttoned up in new photos and videos she shared the day after her Kylie X Kendall launch party and the day of the launch.

In one new video, the youngest Kardashian sister pushed her breasts together in a white blazer with NOTHING underneath.

In a second simmering Instagram Story, she pouted her lips and posed in the revealing outfit.

The makeup mogul also shared two Instagram posts to her grid on Wednesday celebrating the April 6th launch – and the famous family’s splashy ABC interview.

“KARDASHIANS press day, our new show airs April 14th on HULU,” Kylie wrote, showing off her bold blazer look on Wednesday.

“Ok promo,” sister Khloe Kardashian wrote, as another wrote: “Perfect.”

Kylie tucked a thumb into her waistband and flaunted a see-through devil-horned purse with Kendall X Kylie products in tow.

Her fleet of beautiful body-flaunting posts came after Tuesday night’s party and just weeks after her second child, a son, with her boyfriend Travis Scott, 30.

In her second splashy post, Kylie celebrated her launch day after months of hype.

“OMG KENDALL X KYLIE AVAILABLE NOW KylieCosmetics.com! thank you for all the love on this collection. i can’t wait to see all your looks,” she wrote.

She posed with Kendall, 26, in a new flowery photo amid claims that they have both gotten “boob jobs.”

“Absolutely beautiful,” one fan wrote after the rare two-for-one Instagram day.

On Tuesday, the sisters held a party for the official launch of their makeup line for family and friends.

The sisters took over an LA restaurant, covering a long center table with a stunning purple and blue floral arrangement that matched their posh siblings posts.

Each place setting featured a menu with the Kendall x Kylie Collab branding and a matching place card for the special guests.

The famous sisters were joined by Khloe, 37, their mom Kris Jenner, 66, and friends like Stassie Karanikolaou, 24.

The girls have spent ample time on promo for the new line, even creating a new custom-made floral truck as an advertisement.

The Kylie Cosmetics founder flaunted the vehicle on her stories on Saturday, which was covered in the same purple flowers along the top and sides.

Late last month, the mother of two took to Instagram to first announce the project.

The famous siblings both donned serious expressions as their faces were surrounded by purple flowers in their ad, the floral theme blossoming in more posts leading up to today’s launch and this bombastic post-baby look.
