When travelling to our wedding in Y on CO we had to put my wife's dress in the overhead bin. It was fine except for the $&#@(*)%! that saw what it was, shrugged, and shoved it off to one side before the helpful FAs could come over and tell them to put their bag elsewhere. It wasn't a full flight so it worked out, but had it been full we would've had problems as CO's 737s have closets about what you would find on a CR7.
