Most of my clothing is made from Lycra blend fabric that has a lot of give.  To find your size, match your shoulder measurements to this chart. Next, check the corresponding bust measurement.  Your bust size could be larger than this measurement by at least 1-3 inches.  For example, a 36" bust could comfortably fit a size small.  I can take in across the shoulders and bust.  For other exact measurements, please contact me.
