Kylie Jenner Jokes That She Stole A SKIMS Romper From Mom Kris Jenner

Kylie Jenner's latest Instagram photo dump has caught the attention of her big sister Kim Kardashian.

The Kylie Cosmetics founder recently shared photos of herself on Instagram, in which she poses on a grassy slope. Jenner looks effortlessly cool in a gray-mauve body-clinging romper, which features a backless silhouette, and black knee-high boots. She accessorizes sparingly in the pastoral setting, wearing only a pair of black shades, and slicks her hair up into her signature gelled-back high bun.

The romper, as it turns out, hails from Kardashian's shapewear line, SKIMS. The mom of four commented on her little sister's post, "can u tag @skims please LOL."

As of today (Tuesday, January 17), Jenner has yet to update her post or caption with a tag crediting her sister's brand. Though, the makeup mogul did comment back, "@kimkardashian i had to steal this from moms house and now you want me to promote ?!!!! wow @skims."

In another post, Jenner put a sultry spin on après-ski style, wearing a white bathrobe with nothing underneath except a black vinyl bikini from Good American.
