Reality TV stars Kendall and Kylie Jenner will make an in-store appearance at PacSun Santa Monica on Saturday, May 30, at 11 a.m. The first 500 lucky fans are guaranteed a chance to meet and greet the celebrity guests.

According to an event poster shared by Kylie on her Instagram page, fans can start lining up as early as 6 a.m. if they want to be sure to gain entry to the event. The first 500 fans in line will receive wristbands.

In the poster, Kylie wears a V-neck crop top paired with printed shorts. Her sister Kendall is in a white minidress with a pair of roller skates hanging from her shoulder. The girls are wearing pieces from their respective collections, released by the clothing brand PacSun.

Kendall and Kylie have had a long-standing collaboration with the brand. According to a report by the Los Angeles Times, they released their first joint collection in February 2013. They released a brand-new summer collection this year, and the in-store appearance in the Santa Monica, California, store is part of a local promotional tour.

The sisters rejoin forces after having ventured out on their own in the past year. When they were younger, the girls worked on several joint projects, including a collection with Steve Madden and their very own novel.

Since last year, they have started to develop their own projects. Kendall has made a name for herself in high fashion as a sought-after runway model. Kylie, meanwhile, has released her own hair extension line with Bellamy Hair. They have also begun to make separate personal appearances and appear solo in magazine photo shoots.

Though they now have their own careers, the girls will appear jointly to promote their latest PacSun line. The collection features crop tops, shorts, tank tops, skirts and dresses in light fabrics appropriate for the summer weather. The collection also features bikinis and wide-brimmed hats.

The Kendall and Kylie Collection may be purchased at PacSun stores across the United States. The collection is also available online via the PacSun website.
