I am always fighting with bra sizes because a man's chest is shaped differently from a genetic woman. I won't get professionally fitted, so I mist do with the tables online. Some web pages with instructions on how to measure say that you can do it with a bra on, but I don't understand how this makes sense. Is it the band size that I can measure that way? I have a bralette with a very weak elasticated band which hugs me perfectly without digging on my sides, is that the type of "bra" I can use? Given that a non padded bralette may hold things together but it doesn't provide much push, can I use that for the cup size too?

The other question is about support. I understand that a large breasted person needs the bra to hold the breasts and spread the weight on the shoulders and back, but what about small breasts? I may have a A cup or a very small B, not enough to sag or drop. What should a proprly fitted bra do? What part of the breast should touch the bra fabric? Nipple? Underboob?

Thank you in advance for any opinion.
