Couture at the convenience store.

Kim Kardashian's custom Rick Owens gown not only scored her on the best-dressed list at Paris Hilton's wedding, but also earned her the title of most glamorous patron (like, in history) at the mini mart she swung by following the nuptials.

On her way home from Hilton's lavish ceremony on Thursday night, Kim made a pit stop at a convenience store still wearing her black-tie attire. The reality star was photographed strolling through the parking lot in a plunging black ballgown that split at the bust and featured a large cutout below. She paired the dress with Balenciaga accessories, including black hoop earrings, coordinating booties, and a boxy clutch.

She wore her long dark hair in a braid that hit below her butt, and complemented the monochromatic look with dark smoky eye makeup.

According to a source at E! News, Kim and Paris shared some "very cute moments" together ahead of the ceremony. "Kim had a sweet pep talk with Paris and helped her with her dress," revealed the insider, referencing a photo of Kim fluffing the train of Paris's Oscar de la Renta wedding gown. The source added that it was "important to Paris to take so many photos with friends and document everything, every little moment for memories."

"Overall, it was like out of a movie. Everything was gorgeous and it all came together so seamlessly," they continued. "She wanted to keep it incredibly intimate and personal and every person in attendance had a special near-and-dear place in her heart."
