Apparently. Me that is.
At least I went shopping for a new bra today. I didn't buy any. It seems that as a C cup I can now only buy boosting enhancing type bra with padded cups or a sports bra. I just wanted a standard underwired model, maybe with a bit of lace.
Now peering down my front and standing sideways in the mirror I don't feel under-endowed. A reasonable boost northwards is always welcome but there is a bust that I ... umm.... thought.... was adequate for the purpose.... more or less....
Not so according to the bra manufacturers.
