Tank measures approx arm pit to arm pit-12 inches ( laying flat), Total length top of strap to hem bottom, approx 20 inches, straps from top to bottom, laying flat, are 9 inches approx, ( I found the straps long on me but with a couple of stitches they can easily be shortened) ,bottom hem of tank laying flat ( left to right) is approx 14-15 inches wide totalling approx 28-30 inch waist, however this does stretch a little. Triangle shapes throughout. Cardigan measures from arm pit to arm pit laying flat, 18 inch approx, Length from top of shoulder to hem bottom, approx 17 inches, waist is approx 30-31 inches again stretches a little. Can be worn loose or fitted, forgiving. Please keep in mind this is a vintage item and may have very slight yellowing but this does not affect the beauty of the item. Was stored very well over the years. Please view the measurements carefully before purchasing, because it has no label to indicate the size.
