So my fiancée is adamantly against my wearing the kilt to our wedding. I think she should wear her qipao and I my kilt, but she doesn't think that appropriate Regardless, I'd still like to wear something that throws back to my ancestry. What would my options be?

In particular, I wanted y'all's opinion on wearing a fly plaid with a tux. Is that doable, faux pas, or just plain NO?

Other things I've considered are either a tartan waistcoat or cumberbund.

Anything else I might be able to get away with?
