Some good ideas, thanks!

Luckily I do have a black Braemar jacket with black buttons. The plain black sporran looks fine with that (and to be honest, will almost certainly be dressed up enough for anything I'd be attending). My vanity just got the better of me with the Prince Charlie

In cavscout's 'superman suit' photo the cantle on the dress sporran seems to balance out the mass of buttons on the PC, it works well.
