Ordering apparel via Facebook has been hit or miss, this is definitely a hit :-) 5'7 120lbs, purchased small in dark gray, literally am wearing now as I write review. Comfy fabric, not too thin or thick, for lounging indoors and stylish enough to rock outdoors without looking like you're wearing pajamas. Have a long torso with shorter legs so pants are high waist fit for me, but am able to fold waist down without it looking bulky/feeling uncomfy. Will definitely purchase more sets in different colors though, truly am loving the price point and the actual quality. No loose threads, even/clean stitching, and not see through!
