This is a wonderfully quirky and comfortable birds-on-a-wire casual blouse for those relaxing nights out or cool fall days. The long sleeves button up to a 3/4 length and the back falls slightly longer than the front. The width from armpit to armpit is approximately 21 1/2” laying flat. *note that measurements are taken flat and should be taken as a a guide and not an exact fit. Each body time may have different results with fit when worn.
