That is a Strangely Unambiguous Interest
Quick version, this lady-to-be was such a domineering person that she demanded every one of her bridesmaids be precisely 5’10” tall. No taller, no more limited. Also, indeed, that expectation incorporated her companion, who was really 5’3″. The main idea was for her companion to go to the function in seven-inch heels! We don’t have any idea how the issue was settled; maybe her companion got a few braces and figured out how to stroll in them.
