Then we saw pictures of the two on a private jet to the DNC the same night, and it dawned on us: When did Kim and Rachel become besties?
In her latest interview with Stylelist, Rachel spoke about where she seeks style inspiration, and explains her relationship with little miss Kim Kardashian.
On putting together her looks:
"I don't plan too much in advance. It all depends on how I feel that morning. I dress on emotion and let that lead the way for what I wear and how I do my hair and makeup. I like the feeling of being a chameleon."
On how her daughters with Dame Dash inspire her designs:
"Ava wears a lot of my RACHEL Rachel Roy collection -- she's a muse to me with how she mixes it. I really believe in taking risks to create things that feel authentic and individual. I think if you stop trying new things whether it be with fashion, food or the world, then you tend to get stagnant."
On her relationship with Kim Kardashian:
"If you confide in her, she will never tell a soul."
When you grow up with that many sisters, it isn't hard to learn how to make gal pals!
