A year ago, traveling through an airport in the United States, I did the usual removal of belt and shoes to get through the TSA checkpoint to enter the terminal.
I typically wear relaxed fit jeans. The problem is that when my belt is off, my jeans start to sag.
Next up was to get scanned by the human x-ray machine. I can't remember the specifics, but something went wrong here.
Coming out of the machine, the TSA agent spoke a canned response of how the machine detected an object in my pants. He asked if I was carrying anything and then told me he would have to do a pat-down. To make a long story short, I got frisked right there in the line including him grabbing my crotch. And then I was on my way. It was somewhat humiliating, but I got over it. But it is not an experience I would care to repeat.
I'm traveling again this week through the same airport. What's the best thing I can wear to avoid having a similar incident? I've seen folks go through the airport lines in gym shorts, sweatpants, or even pajamas. I'm not sure if looser or more tight fitting pants improves my chances. I've got some different pants I could try to, or could buy something different.
What would you wear to avoid the x-ray machine setting off a false positive?
I'm an average looking man.
Update
Thank you for all the great answers.
TLDR: Pull up those pants and empty those pockets is what worked for me through the terminal entrance this time. Although the officer needed to do a pat-down hand sweep over my waist, it was completely within bounds and appropriate. At the return trip airport, they waved most folks through the metal detector instead of the wave scanner. I do believe certain airports are more efficient at getting people into the terminal.
