I'm with Steve, a picture or link would be very helpful.

It really depends on the sporran and how far you are willing to dress it down.

In this recent picture I am wearing a semi-dress sporran with daywear



I think I pull it off. Now if it was was a fur and cantled model I think it would be far to much.

Here is another picture of me with the same sporran which is much more daring. I am trading off wearing a more formal sporran than the outfit should have in order to make an ensemble that is a study of black and silver.



It can work (in my opinion) but the devil is in the details.

Cheers
