Kim, who has been very vocal about her weight loss journey
since giving birth to her and Kanye's second child, Saint
, in December, rocked a skintight little black dress that perfectly showed off her fit post-baby body
while heading to dinner. She accessorized with black heels and a chunky choker that was given to her mom, Kris Jenner, by the late Nicole Brown Simpson
. In typical Kim fashion, she took to Snapchat to give her fans a close-up look of the jewelry, which featured a stunning cross pendant.
