I don't know; the Bra Lady was more (as THA SUGAH RAIN said) into the esoteric nature of bras and bra fitting. The Bra Lady cared more about the bras than the breasts in them. This guy may appear crass, but he likes breasts and wants them to be happy and comfortable.
You all mock, but Mr. Bra's family has been in the brassiere business for generations, ever since his great great grandfather Thaddeus Bra invented the garment.
