I suppose I may be the only Highlander still awake on this forum since it is now 4 in the morning. In the Highlands we rarely wear head gear with Highland dress so his isn't an issue today. Never, ever, ever would we wear head gear within doors, so that part isn't at issue, either. But if we do wear head gear with Highland dress it will always be a Balmoral, so I can answer that part of your question specifically. On the hat rack or on the hall table. Never under your epaulet if you have one, never stuffed in your jacket pocket (inside or outside), never in your waist band or in your sporran. For you Americans think cowboy hat -- where do you put it indoors? On the hat rack, right? Oh oh, I have just heard you say "no, on my head." Shudder.
