Welcome to the forum! If you're not looking for a black Prince Charlie or Argyll jacket, then grey tweed would certainly look all right, as Fr. Bill has said.

I'm a big fan of lovat green tweed (the color you see in my profile picture) for an Argyll jacket and for kilt hose. I think it would look terrific with a mostly red kilt, and would open you up to hose that are not black or grey or cream. There's a little bit of the peacock in Scottish attire, so let your imagination run a little.

As far as accessories like belt and sporran go, you'll naturally gravitate to black because of the kilt color, but don't let yourself get stuck there either.

Depending on the color tweed you choose for a jacket, a brown daywear sporran might look really sharp. Many members (myself included) rarely wear a belt (the kilt is designed to stay up with the straps, which means the belt is decorative). Don't feel like you necessarily have to have a belt at all.

But mainly, welcome!
