5’2”, 150-160lb, got xs and feel most comfortable.

I bought the purple in a size small and it is way too large but I love the quality so I quickly bought the pink in a size 2XS and it is still really large on me, but I will keep it since it is 80% cotton and great quality and I prefer cotton material. I am 5'2" tall, weight 100 lbs, chest 34" waist 27" and hips 35" and I am an older female who loves comfort while sitting around the house and quality. The overall length is the same in the size small and in the size 2XS and the sleeve length is the same, too. Really GREAT quality!
