The only "rules" for the bow tie are that it should best match the lapel facing in both color and fabric; e.g., black satin or gross grain for both. And that it should always be black even if the jacket has self faced lapels as might an ivory dinner jacket worn in tropical climes.
The shape and style of the bow tie, assuming it balances well with the width of your face, has always been an area acceptable for both experimentation and the opportunity to be fashionable or different; with the above assumption that the fabric of the bow tie is a close, if not exact match, with the facing of the jacket lapels.
Hope this is the license you seek for finding your own personal style. Just make sure that the width and height of the bow tie suit your facial structure without seeming too small, big, or otherwise disproportionate. You fiance can help you with this, if you lack another confidant.

Thoughts?
Thanks for your help!
