I think nowadays if DBH tried to buy me sexy underwear he would find all the cheeks of his boxers cut out.
Brenda do you mean they go to the side of the cup, sort of at the back? I obviously haven't investigated bras enough lately, I wear t-shirt bras. They are fine when new, but I have to be really careful not to stick them in the tumble-dryer by mistake or the next time I wear them, my cup runneth over with a vengeance.
Also I have to make sure that the central bit between the two cups is reasonably substantial, I have known it to come apart on more than one occasion. Really embarrassing if you are out for the day.
