I don't get Vests.

This is completely random, but I have to say, I don't get vests.  I get a lot of catalogs and emails from clothing stores, and they seem full of vests this year.  While they look nice, I can't stand them.  Why does anyone like to have their arms freeze while their upper body boils?  Frequently, I find myself putting on and taking off a sweater over and over again, because my arms are cold, but my body is warm.  A vest doesn't help this situation.
