I just got back from Hawaii, and in the course of the trip went through about 6 check points. I wore my new black leather R kilt. Lots of metal!! buckles rivets and snaps, d rings and dog clips. A couple of times I didn't set off the alarm. On the times I did, they asked for a male assist. Took a few minutes to wand me down, then they had to pat down the kilt to check out the metal bits. Had a new kid in Kauai, He was very nervous, and a little rude. He had a female supervisor who actually took him to task on his manners. I guided him through the process, as I was getting used to the process and knew what to expect, and never once did they wand inside the kilt!
Once on the plane the stewardesses loved the leather and grabbed a feel.
It's an OK experience, go for it.
