It’s a set . J.crew cotton relaxed sleeve, boat neck sweater and lounge pants

I bought this for lounging. Worked out great last year but now I lost weight so it’s a little too big now. This is a heavy cotton. Not heavy warm, but the cotton is heavy. Like a true beach sweater. It does drape nicely over your chest. In one picture I am wearing some J.Crew elastic waist pants that match nicely. They did not come as a set, but its a good match. I will throw in the pants for free. They are made of cupro, lightweight and non stretch. Sweater measurements Pit to pit 20 inches Length about 23 inches. Sort- of cropped and boxy.
