Looking very good, Michael. I am sure your bride will be proud of you.
As for your hose choices, I am a bit uncertain about both the red and the grey. The red seems a little bright compared with the tartan, while I have a general dislike for grey (especially with tartan).
Personally I would suggest a more subdued red, or alternatively a blue or a green (both somewhat subdued) rather than either.
After all, you have eight months to get the details sorted out.
But if the choice comes down to the two pairs you have, I would reluctantly recommend the grey.
Regards,
Mike
