Yesterday at an unrelated club meeting I noticed a guy that was wearing a bra. The back was actually quite visible through his shirt. I did not say anything at the time and I do not believe he was trying to show it. Because of the way he seemed to stay separated from the rest of the group. I feel as though I missed my chance by not saying anything yesterday, But I did not want to start a scene or out him to the group.

How should I approach him to let him know we share another hobby.
