"I think we all feel very connected because we’re all going through this together. The world feels less pressure to get dressed in the morning, which I think is a good thing. Being able to feel confident in sweatpants is one of the greatest gifts."Kicked Off Instagram Book CLubJoining the likes of book club hosts Reese Witherspoon and Oprah Winfrey, Kaia upped her BC game last year. She continued:"I think everyone should have a book club. That’s why we’re doing Slave Play this month because it ties back into culture.
