This lounge set from the Nordstrom anniversary sale is one of my favorite purchases. Both pieces are SPANX, and they are in the airessential fabric that we love so much. I went up to a medium, in both the shorts and the top, and I think that was the right choice. Make sure you size up. My new balance sneakers have already sold out, but I linked similar options below.
