So we entered into negotiations.

I've used a plethora of the advice gained from this thread. I showed her pictures of how smart a kilt with all the trappings can look. I showed her a handfull of tartans I can "claim" affiliation with and let her pick out her favorite. I even went on to the Scotweb site with her and let her pick what "look" she liked best.

Gentlemen, I do believe she has come around.

I'm not declaring victory just yet. My girlfriend's mind has been known to change like the wind. Plan for now is to not press the issue and simply hope that me wearing a kilt remains a viable option in her mind.

Thanks again for all the advice!
