Ok so recently I had to go shirt shopping for work, so guys shirts. Now I've been on HRT for about 3 and a half months and before hand I wore a 16 1/2 collar since my actual neck measured 16 1/4. These are facts from many fittings and they never changed. So it occurred to me when shopping that HRT may have shifted things since the neck is made up of so much muscle. I got remeasured and sure enough I went from 16 1/4 to a 15 inch neck! I'm curious on what other have experienced, any thoughts on how much further it will go down?
