Congratulations for pushing your boundaries and enjoying that wonderful feeling of the hug a bra gives. Glad to read you took control of your fear and realized no one cared what you were wearing under your clothes because they really don’t know or care. I hope you wear your bra more often and become comfortable with it. Some bras are more stealthy than others.
I under dress with a bra every day and its become normal where I feel it missing on the rare occasions when I can’t wear one. I never even think about what others see or care what they think anymore. I’m sure some might see the outline but no one has ever said anything. I haven’t been called ma’am yet but some women seem to be more chatty than normal and I wonder but its all good. I even wear small forms when its cooler weather.
