My wife took me to the shop she visits for a professional fitting. It just happened that the owner was a personal friend of hers and had know me for years. It was a full line foundations shop, aimed more at fit than fashion. As most of the sales help had never fitted a male before, I was asked if they could assist. Of course I agreed. It was all very professional, they all measured, tucked, and poured me into everything in the shop and found that the tape can lie about your true cup size. It is more that just how far you are 'out there', it is also how pointy you are, how high or low you hang, the shape of your shoulders, and what style of clothes you will be wearing. Of course, it cost more dollars that off the rack at Wally World, but it was an eye opener for us. Everyone with breast tissue should be fitted, whether they are presenting as male or as female. Some males want to minimize their profile, I sorta like showing off!
