Congratulations John, I hope it's an event to remember fondly and that married life suits you both
If the lady is wearing elf type attire why not wear something that will be comfortable and still look appropriate.
Trews, tunic, cloak, belt and pouch, cloak pin and belt fastenings and the like with a common theme ? Natural fibres, silk, linen, wool, leather, silver, our own rose gold or bronze.
Pick a tree, oak, holly, birch, elm, rowan.....and use that as your colour, motif and perhaps spiritual meaning.
If you choose a native tree then I can send you a shade card of the colours that I get from it. Fabric in all the natural dye colours can be obtained from the people who supply re-enactor's.
The leaf could be used to design the decoration of your belt and pouch and knife sheath, and if you used a knotwork incorporated into the design that could be used to create your cloak pin too.
I'm not offering to make the garments (kind of swamped just now ) but I'll happily draw out sketches and patterns for you, and give details of companies who would sell appropriate fabrics.
Depending on how keen you are, you could probably get everything made yourself or commissioned from folks on the forum. Shoes/ boots/ belt/ pouch/ sheath/ cloak pin......probably even a torc
Best of luck with it all,
cheers,
Toddy
