Preface: I wear a bra and panties every day, most days, depending on the shirt I choose, with a subtle pair of breast enhancers. Nobody notices or cares and it is all good.
My ex took me back to court to have my child support adjusted. When I entered the court building there was a security station with a metal detector.
I emptied my pockets and put everything in the little basket to go through the scanner and walked through the detector. As always, it beeped. This is usually due to the metal shanks in the arches of my boots.
In short, the hooks on my bra are what set the alarm. I didn't realize those things were that sensitive.
To his credit, the Deputy was a consummate professional. He asked if I was wearing a brace of some sort. I told him yes and he apologetically said he would have to check, ran his hand across my back, nodded and said I was good to go.
No doubt that he knew exactly what was going on but he never indicated anything out of the ordinary.
Don't know if he told the other deputies or not but there was never a comment or a sideways glance.
So, I guess the takeaways are; sports bras only on court days and, as has been said a thousand times on here, nobody cares.
