Each of us have our own views. The blue shirt and the brown sporran works with the total outfit (including the dark hose). I understand why others think the jacket is too long. It draws attention from the kilt. A black sporran would be more exact but do we all have to comply when what we have for gear is fine?

Does everything feel comfortable? Do you like the combination? Does it fit the moment (when a jacket is needed)? You can always change if you find this combo doesn't work for you in the future.
