The 16 fits you much better but you have to be comfortable..
I tend wedge it up my arm so it doesn’t hang and move around at all. I am only borrowing it for a day. Until I decide 15 or 16, I have not been wearing the 15. The 16 is definitely less noticeable and I don’t seem to fuss with it as much so far. Work tomorrow may be more telling at my desk.
Yes the sizing game can go on forever. My husband joked to just keep one in each size. Lol.
Here’s the 15....definitely more fitted but it fits....
