Hundreds attend Kylie Jenner's Kylie Cosmetics pop-up shop at Houston Topshop

HOUSTON – Makeup gurus and Kylie Jenner fans, get ready to put on some comfortable shoes -- Kylie Cosmetics is in Houston!

Houston Topshop was one of seven stores across the nation to host 20-year-old Kylie Jenner's Kylie Cosmetics pop-up shop on Nov. 20.

Doors opened at 10 a.m., but fans lined up outside The Galleria mall around 9 a.m. to get an early start.

More than 500 wristbands were handed out to customers to get inside the store. Some of Jenner's biggest makeup fans and their parents were there waiting in line for hours.

Customers told KPRC2 that they were Christmas shopping and getting some items for themselves that they weren't able to get online. Employees said the pop-up shop had 16 exclusive items only available at November's pop-up shop.

Topshop's officer manager, Sara, said the store will continue to carry the product until it runs out -- which could happen in hours, based on prior pop-up shops.

Topshop's general manager said they will restock after products run out in the front of the store. He said they expect to run out of product by the end of the day, but Jenner is planning to have two more pop-up shops, with one in December and another in February, for the people who couldn't attend November's pop-up. 

Kylie Cosmetics are only available for purchase online and usually sell out within minutes after relaunching to the site. The pop-up shop gives Houston's makeup gurus a chance to finally get their hands on those popular Lip Kits. The $29 Lip Kit provides a range of colors, but Kylie Cosmetics will provide eight new shades exclusively for Topshop's pop-up shop.

Jenner has been known for her plumped lips, which led to the Kylie Jenner Lip Challenge, overline lips and, now, a cosmetic line that has turned into a million-dollar empire. According to Fortune.com, Jenner's Cosmetics is expected to become a billion-dollar empire.

In the past, Jenner showed up to her pop-up shops to surprise fans, but she's recently been out the spotlight after rumors that she is pregnant and that the father of the child could be Houston native Travis Scott.

Several other pop-ups will be held at Topshops in New York, Los Angeles, Las Vegas, Chicago, Atlanta and Miami Aventura.

There's no word on whether Jenner or Scott will make a surprise visit to Houston; fans can only hope.
