I can say this from living on both sides of the coin and points in between that men and women notice. However women do size you you up more often than men. I've always (since puberty) worn a bra. I, at one time did make attempts to hide my breasts and the fact that they were held in place by my bra.
Before transitioning, I worked as a nurse's aid in a hospital. My scrub tops had a v neck. Unless I wore a cami under it, there was a really good chance that someone, whether it was a patient or co-worker, would have a really good idea of at least what color bra I was wearing.
Its much easier nowadays. I'm expected to wear a bra. Bras come up in conversations at work and lunch AT LEAST once a week. Its no longer "OMG! Are you wearing a bra? ". It's more like " Have you tried tried Elomi's Matilda? " or another bra.
Love you guys ♥️🥰🤗😍😘
