So yesterday, I had to fly to warmer weather for a training for work, and, being active military, I was able to do the TSA Pre-check. So, I figured I would be able to underdress with no issues. Get to security with the bra, panties, and nylons. Walk through the metal detector, and agent says, you're good... Oh, wait a minute, you've been randomly selected for additional screening. Now, keep in mind, I purposely picked a bra with no metal, and front closure, so as not to set off the detector. I end up walking into the scanner where you have place your hands over your head, scanned, and walk out. "Some areas" popped up on the scanner, that would require the male agent to do a pat down. He gets to the closure and asks, "Do you have something there?" What to say, no? Not to cause too much issue or anything, I say, yes, a bra. Then he has to pat my buttocks. Of course, he had to go under my t-shirt, so I know he felt the panties, and the pantyhose. He clears me, and says, ok, you're free to go. The walk to get out of the area took A LOT longer than I wanted. I think tomorrow, when I fly back, I won't wear the bra until after security!!
