BiB - Ariel and the Trick Buckles
I invited my friend Ariel over, and she showed up in a black vegan leather romper that zips up the back (from La Redoute), and black boots. As always she had tea with milk.

The reason I asked her to come over, was that I wanted her to try a new pair of short overalls (from Common Sense) out for me. Actually I had modified them, but that I hadn't told her. (Since it was sort of a proof of concept, I hadn't spent too much effort on making it look perfect.)
They were actually a fair bit too big for her, so she decided she could just wear them over her romper.
When she got to the buckles, she noticed they were unusual, but putting the halves together they snapped closed easily, so she paid them no further attention.
Being the helpful girl she is, she extensively showed me the overalls from all angles.

Since they were still quite wide on her, I let her add a small belt to them. Since these shortalls don't have belt loops, just putting a belt over them is not so 'safe': the wearer could just slide the fabric down under the belt without needing to open it. So I asked her to weave the belt through the top buttonholes at the sides. That would make them unremovable when putting a little padlock on the belt, but since Ariel still didn't know my plans with the shortalls, I didn't add a lock this time.
She actually suggested an alternative way to wear the belt: by looping the belt from behind through the buttonholes, and then back again, the belt is double at the back and not in the front, pulling the fabric at the front close to her body. I actually liked that look, and adding a padlock to the belt would make this version just as safe as the regular way, so we kept it like that.

Ariel kept the overalls on for a while longer and we sat down again to chat some more. But gradually her attention returned to those curious buckles, and she started wondering how they would open. She couldn't just pull them apart, but there were no buttons you could press or any other hints on how to open them. She fiddled with them for a while, and then realized I had tricked her and she wouldn't be able to take them off herself.

Then I gave her a challenge. These buckles I had removed from locking child wrist leashes (see my strap fastenings page for more details), and those leashes can still be used without the locking buckle. But of course the wearer could simply undo the Velcro to escape.
So I told Ariel I would let her out of the shortalls if she could escape from those non-locking leashes. But of course I made it hard for her by attaching the 'parent' side to opposite ends of my couch, so that she had to pull against the spring in both cords to reach one wrist with the other hand. I then realized that she could still use her mouth to open the Velcro, so I had to add a ballgag, which she hesitantly accepted as part of the challenge.
It wasn't an easy challenge, and Ariel had to work hard to release herself, but in the end she managed to free herself from them.

Then I 'magically' opened the buckles for her and she could finally take them off.
In the end she didn't seem too upset about me tricking her, although she kept wondering how I opened those buckles.

For those who do not yet know how those buckles open: you need a magnet for that. In this case I removed the magnet from the parent bracelet of the wrist leash, in which it was integrated, and put it in an improvised ring of fabric. Putting that ring on my finger with the magnet on the inside, and positioning it correctly above the buckle, it opens with a tiny click.
If you would make something like this with nude-colored fabric, or glue the magnet to say a signet ring, it would be quite inconspicuous.

(Note that in the Marson story of contributor Klaus (in German), he came up with the idea of overalls buckles that need a magnet to undo, and a magnet integrated in a ring to unlock it. At that time he was fully unaware that those buckles actually exist, but once I discovered those wrist leashes that have them, I wanted to recreate his idea.)
