Some folks have used the sporran patterns here -- search "troop 7" and you might locate reviews. One fellow said be careful matching up the holes front/rear but otherwise worked OK. Maybe not the style you're looking for but a start?

"Kilt pin" is anything you put in that place on the kilt. Use a ladies' brooch, or find something you like and glue a pin onto the back (check Michael's, other craft/hobby stores for glue and "findings," which is what the pin and other jewelry-making stuff is called).

Another thread on ladies' size kilt jacket mentioned using a Spencer style jacket. You can get them from restaurant supply store.

Good luck!
