No...the kilt pin goes thrugh only the top apron and the two aprons are designed to swing independently...you don't pin them together.

I'm sure that this seems counterintuitive but the weight of the material and the weight of the kilt pin are more than adequate to "preserve modesty"...unless the kilt material is really light weight, of course. Try it and you'll find out that it does actually work that way. Even the PV material that USA Kilts uses and whch they refer to as "11 oz." has enough weight to stay in place in a stiff wind with the help of a nice pewter kilt pin.

If you still need a security blanket...I sometimes augment my klt pin with a large Chicago White Sox button or a cluster of DC comics buttons from the comic con....sorry, all you purusts....just a little extra weight for the insecure.

Best
