There are some perks to being Kim Kardashian's former assistant, like having a super star-studded wedding guest list stacked with famous names. Stephanie Shepherd (who began working for Kim in 2013) recently got married, and everyone from Kris Jenner to Justin and Hailey Bieber attended the nuptials.

Hailey stunned in a baby blue, long-sleeve gown with a high mock neckline from Internet-beloved brand Fanci Club. The model's exact dress is the Mortal Holy Grail Dress, currently available online in black and red, and it features a super low-cut open back with daring side cutouts that revealed just a ✨ touch ✨ of tasteful side boob.

Hailey sported an icy blue Y2K eyeshadow look to match her cold blue gown, and styled her short, bobbed hair into a deep side part flipped over her face.

In photos released by the Daily Mail, Justin can be seen entering the wedding venue behind Hailey in a more casual ensemble. The "Peaches" singer donned a pair of baggy black slacks with an untucked white button-up shirt and no tie.

Hailey is on a total dress kick this summer — earlier, the model was spotted hanging out in Los Angeles with her bestie Justine Skye while wearing a sheer white slip dress.

The midi featured thin straps and a '90s cowl neckline. Hailey rocked the exposed undies trend with a pair of comfy LDMA Low Hide Briefs that peeked out from underneath the see-through fabric, and finished off her angelic look with a pair of white and green dad sneakers.
