Hi Ben,
I'm really happy that you have discovered the comfort that a well fitted bra can provide. I was much younger than most here when I started wearing one however, I do still remember how much better I felt and secretly, how much I liked how I looked. For almost 20 years I had worn a bra every day and thought that wearing the right layers, nobody noticed. It turned out that it was the worst kept secret in the world! It also turned out that it didn't matter. No one cared. The ladies I worked with all knew. They weren't wondering why I was wearing a bra, that part was obvious to them. They were wondering WHAT I was wearing for a bra! Women notice these things. Now, no single bra style will work for everyone, if your chest looks good as a result of the bra your wearing, someone else will want their's looking as good and want to know how you achieved the look and shape.
Women talk and they do talk about their breasts and bras. They say what they like and don't like. They talk about where they shop and they even shop together. I quickly became aware of this after I was wearing a bra openly. My "monsters under bed" all disappeared as soon as I "turned on the light". I discovered that a was being afraid of nothing.
