I had no worries going through customs in Canada but in New Zealand there were two machines and it beeped on me. Something on my side. There was nothing on my side. I lifted my top to show, i had a fabric belt tied around my skirt, maybe that which wasn’t knotted is what triggered. Shrug. I do wonder what that was that had me patted lightly with a guard in plastic gloves. so it goes.
