Wanted Measurement for Feeple65 Girls

I am looking for a measurement for feeple65 girls that is not normally on the list of measurements.

Specifically I am looking for the measurement around the armpit area. So from the shoulder/arm point, under the arm and back to where you started.

Can anyone help?
Thank you in advance.

 

thanks for replying at all....

so if the doll is on the table facing you. Take a measuring tape and place it at the point where the arm goes into the body, so the tape drapes down the front of the doll and the 0"mark is on the shoulder line/arm-joint. Bring the tape down and under the arm and back up to where the tape started. I am trying to understand how big that joint is. I hope that explains what I am asking for.

Also, if it is not too much trouble, can you also measure the bicep? Thanks so much!

 

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
