Paris Hilton & Winnie Harlow Suffer Strange Wardrobe Malfunctions at KKW Beauty Launch

Paris Hilton wasn't the only star to suffer an embarrassing wardrobe malfunction at Kim Kardashian's beauty event because model Winnie Harlow did too.

Coincidently, both A-listers experienced strange "whoopsies" with their fashion choices at the same event on Thursday night.

Arriving to the launch party of Kim and Winnie's KKW collaboration, Paris seemingly forgot that her dress had a sky-high slit.

The metallic slinky number did not stay in place when the hotel heiress began walking into the event, held at L'Avenue at Saks in New York.

To add to that, Paris did not appear to be wearing any underwear, which is rule #1 when wearing a daring dress.

Winnie is used to quick wardrobe changes and making sure she doesn't suffer embarrassing tumbles on the catwalk, so how did this happen?

The model got out of her car and struck a pose outside the location and (shocking), her tiny strap magically slid down and exposed her left breast.

Thankfully, she had a mesh sheer shirt underneath but photographers still got a show.

Once inside, and away from shutterbugs, Paris and Winnie did not seem to have any other issues with their wardrobe.

The girls mixed and mingled with guests at the event and stopped to pose with the lady of the night, Kim, and her BFF La La Anthony.

Kim shocked fans too when she was spotted letting loose with a glass of champagne.

The KKW Beauty founder hardly ever drinks, so it's good to see the mom of four having a fun night with friends!

Kim's newest cosmetics collaboration, KKW X WINNIE, launches today at noon PT.
