Rebecca Minkoff's Must Haves, From Daily Probiotics to Her New Book

"I recently added this beautiful bookcase to my home, and it's as functional as it is stylish," Minkoff says of the Castlery Posey Shelf ($999). It's fitting that she'd invest in such a gorgeous bookshelf since she's been focusing on her book launch first and foremost. This piece features elegant curved panels, round poles, and solid oak edges, and it comes with a one-year warranty and 14-day return policy.
