Not thinking I did a dumb thing. I was under dressed while traveling. I was wearing a cute pink bra with matching panties. I often wear them as l feel normal in them. Not thinking I went to the airport. While standing in the TSA line it dawned on me what if their machine sees it! I stated to get nervous but there was nothing I could do as I was in line and had to get on a plane. Well the machine saw through my outer clothes. This caused the TSA to pat me down. The male agent used respect while he patted me down. Once on my back found the bra clasp then traced it until he found the shoulder straps and then traced them until he figured out what it was. All he said was OK you are all set you are free to go. I was just mortified. I will never ever put myself through that stress again. I was so upset with myself how I could be so careless.
