People wearing form-fitting club dresses in Vegas.

On Friday, the sisters made a surprise appearance at the Las Vegas Summer Kickoff event to promote their respective beverage brands. The duo wore skintight dresses that were perfect for Vegas clubs. The founder of the cosmetics company styled her look with black heels and sunglasses. The model left her hair down in a middle part and hid her diamond earrings behind her ears. The sisters wore black and red for their photos, and it looked like they were inspired by a Las Vegas poker table.
