Khloe Kardashian revealed her hard work at the gym has paid off when she stepped out on Wednesday, flaunting a more slender frame.

Kardashian made a stop at her DASH store in West Hollywood on Sept. 26 wearing a super chic casual ensemble that revealed her recent weight loss. (See the pics and video below.) 

The Keeping Up With The Kardashians star wore her hair slick back with sunglasses to accessorize a head-to-monochrome look. Her black satin baseball jacket with black skinny jeans and black pointy toe Christian Louboutin pumps was a hit in social media; less than 24 hours after she shared picture of the look on Instagram, she garnered almost 365,000 "likes."

She revealed on Instagram that the look was inspired by the 1970s hit musical movie Grease.

"Grease lightening look today!!! Shout out to@robscheppy @clydehairgod #DASHDay#ThunderBirds #Grease," she wrote.

Three weeks ago, Kardashian's younger sister Kendall shared pictures of them working out at the gym together on Instagram.

She captioned the pictures of them wearing workout gear at the gym: "KhloMoney and Kenya gettin it in in the gym, stunna style" and "action shot! KhloeMoney workin on that booty#GetItGirl."

Kardashian arrived at the store days after she joined her sisters Kylie Jenner, Kendall Jenner and Kourtney Kardashian on a trip to Las Vegas. They went to see performances at the iHeartRadio Music Festival on Sept. 21. The sisters all wore black and posed on the red carpet after they arrived holding hands. They later met Miley Cyrus backstage.

Khloe took a photo of herself with her sisters at the concert and captioned it, "Sisters are everything! ❤#LeatherMoment #iheartradio." In the pic, she was wearing a skin-tight leather cropped top and pencil skirt.
