5. Stretchy and sculpting leggings

High-Waist Airlift Capri, available at Alo Yoga, $104

I know these leggings are pricey, but I've recently adopted a "fewer, better" mentality that has helped me justify the cost. These are my perfect pair of leggings: They're compressive but not restrictive, jet black and not at all see-through, and they have a waistband that doesn't dig in but doesn't ride down when you're bent like a pretzel during yoga practice. —Sally Kaplan, editor
