I'm 5'5\"\" 155 lbs. Ordered a medium. Roomy, relaxed fit, without being sloppy. A nice pulled together look while being comfortable. The fabric is a good weight, but I haven't worn or laundered the outfit, so I don't know how it will hold up, but even when it is no longer in condition to wear for errands, lunch out, visiting friends, etc, it will be great for lounging at home, so I think it's good value for the price
