Kardashian, 26, was in Las Vegas for the launch of his Arthur George by Rob Kardashian line of socks at Neiman Marcus on Saturday.
Wearing a suit and sunglasses, Kardashian showed off a slimmer figure as he greeted fans who flocked to the department store to meet the reality star.
When Kardashian first embarked on his weight loss journey in February, he chronicled his workouts and diet on social media. Then in March, Kardashian told PEOPLE he was working out twice a day, once with a trainer and once with friends, adding that he hoped to be 200 lbs. by the Fourth of July.
