Not sure about it

I agree with a brown sporran with those shoes. I think a cream tie would look good with a darker (even maroon) shirt. I don't have any problem with the three buttons on your vest. All of mine have five buttons except my scarlet one with three that has a low cut neck line, then the shirt and tie draws the focus. I like this look on you.

I like it. I like the three button pattern. If you think it a bit much, could you try a solid waistcoat? It might depend upon the occasion if you go bright and beautiful or more subdued. Wear it often in good health and happiness.

Nice look.
