The piece: Westward Leaning Mercury Seven Sunglasses
The price: $180
Why we want it: We already credit Westward Leaning with crafting some of the coolest sunglasses on the market — and we're pretty sure these celebs do, too. Now, the label we love is partnering with Barneys New York to deliver two exclusive styles — including this perfect take on classic tortoiseshell — and while Westward always donates $10 of every purchase to charity, these styles will benefit a special cause. All donations from the purchase of these shades will be made to the National Science Teachers Association (NSTA), so you know you can feel as good about buying them as you will wearing them.
