HI , the sleeve is s low raglan. the pit to pit measurement is shaped like a dolman. i measured at the curve of the sleeve. size xs pit to pit 43" across front and back bottom hem 37" size s pit to pit 43" across front and back bottom hem 38"

Thanks for your message. The measurements for bust across the chest, and width across the hem are as follows: S: Hem circumference 44”; 25” armpit to armpit measurement (50” circumference) M: Hem circumference 46”; 26” armpit to armpit measurement (52” circumference) L: Hem circumference 48”; 27” armpit to armpit measurement (54” circumference) Please note the sleeve is a Dolman, so it has a very low cut under arm and a drop shoulder. Across the chest it fits wide and loose, so the armpit to armpit measurement falls below the bust and is not a good indication of fit. The style is meant to fall off the body for comfort and a beautiful drape. Please let us know if you have any more questions!
