I never tied actual numerical measurements to my measurements.. BUT... the day before my surgery I pulled out some string and wrapped it around my belly, hips, thigh, arm, etc. and cut them exactly to the size.. I attached masking tape to each piece to label what was what measurement and keep them all in my backpack. I pull them out every now & then and can re-wrap around each place and see the MAJOR difference in size. Though I've never actually measured, I still can compare so easily.
