What is one interior-design must for those of us in need of a quick-change?

Lauren: "People sometimes overthink paint colors and get sucked into that whole 'accent wall' situation. If you’re stuck in a paint-color rut, I would recommend painting your walls a light warm gray and making sure your trim is a bright white—it will freshen up your home."

Sasha: "You cannot go wrong investing in a gorgeous, over-sized mirror to liven up your space. It functions like a piece of artwork and immediately adds architecture to the space."

On Lauren: Marni Skirt, J.Crew button-down, Manolo Blahnik booties, vintage necklace.
On Sasha: Derek Lam Blouse, Chloé wide-leg jeans, Bottega Veneta raffia wedges, vintage gold chandelier earrings, vintage gold cuff with green stones, Hermès Birkin.
