I'm taking my fiancée to a five star restaurant on Tuesday evening and I'm wondering what would be appropriate. I have a dark navy suit jacket, red button front shirt, black or navy tie, my Kerr Modern tartan kilt, black kilt belt with silver waist plate, bottle green socks and black shoes. I also have a black Spencer jacket with silver thistle buttons and matching vest, white pleat-front shirt, black bow tie, Kerr Modern kilt, bottle green socks and black shoes. I'm wondering which outfit would be more appropriate.

Thank you.
