In her photos, she displayed their similar but different luxury purses, car keys, water bottles, sunglasses, jewelry and wallets.

Kylie Jenner shared some stunning selfies from her day with Kendall Jenner on Saturday

The 26-year-old beauty mogul took to Instagram to post some sweet photos of her and her older sister with their cheeks pressed against each other. She also shared a series of snaps on her Stories showing off her and Kendall’s differing tastes with their most commonly used belongings placed side by side

She documented her day with her sister with selfies of them pouting and also with bright, teeth-baring smiles.

The duo also appeared to be wearing identical makeup with rosy cheeks and a mauve pink pout — which she later specified was a lip liner from her makeup brand in the shade Comes Naturally.

After showing off their similarities, she started showing off their different tastes in her Instagram Stories.

In a series she titled ‘ky vs kenny’, she first snapped her bubblegum pink, leather woven tote bag laying on a table next to woven slouch purse in a mustard-colored, velvet material.

She also posted a snap of Kendall’s Porsche car keys next to her own Bugatti’s.

Kylie also shared a photo of Kendall’s bright yellow, insulated Chris Stapleton water bottle next to her pink and bedazzled one.

A more identical comparison was her photo of their oval-shaped, retro sunglasses sitting side by side on her marble countertop.

She also posted a snap of their jewelry side by side with her many silver rings and hoop earrings next to a chain-linked, vintage gold watch.
