The athleisure trend has been going strong for some time now, and it's easier to incorporate into your wardrobe than you might think. While it's natural to veer toward donning sportswear pieces from head-to-toe (hoodie, sweats, and sneakers), these separates also work well with more au courant wares. Proving that notion is Ashley Graham, who paired track pants with a cropped sweater by Proenza Schouler. The addition of strappy heels makes it a breezy yet pulled together option when the invite says smart casual. On top of being supremely comfortable, add super versatile to the list of athleisure's accolades.
