Wow, thanks for all the comments and input! Glad to see the question has created such a great conversation.

I've decided to go with the "traditional" 3 button as suggested above since it will be used primarily on formal occasions, for the next year anyway. After that, I'll likely invest in a less formal Argyle or Crail option.

I'm (not so) patiently awaiting the phone call from the Kilt Maker to tell me it's ready to pickup... any time now Pictures soon!

Thanks again!
