Is this jacket or a shirt/dress? If it’s a jacket, You can take it off and put it through x-rays. If it’s a shirt/dress, I’m not sure of the consequences of walking through security naked or in your underwear…

Wouldn’t you just put it through the xray and then the TSA will pull you aside if needed?

I haven’t been to an airport with in years where only one person at a time can unload their stuff into the x-ray machine, usually they have spots for five or six persons.

This is not an issue:

I’ve done ziplock bags for cargo short contents before, speeds security checks up a lot.
