I ordered size medium. the fit is true to size. the color and pattern work beautifully with the delicate yarns and design of this sweater. as other reviewers have stated, it is very thin and lightweight. in my opinion, it serves more as an accessory rather than it being functional as a cardigan worn for warmth. when i tried it on, i considered whether it would provide any warmth at all...summertime air conditioning, etc. the answer is no... if i decide to keep it, it will be for its aesthetic...
