I have a few shirts that I modified last year when my collarbone was broken that I'd be willing to loan to anyone with a similar injury who might need them. I cut the shirts and sewed in a separating zipper from the front button placket across the upper chest and down the sleeve. These shirts can be doffed and donned without moving the right arm or shoulder and with the right arm in a sling. Size is women's medium. I hope nobody needs these, but if you do, they save alot of pain (and potentially alot of stink). If you need a different size or a different shoulder, I could send you directions for the modification. I might even do it for you if you send me your shirts. Just something to keep in mind if you ever need it.
