I have a question for those with traditional style kilts with pockets.

For starters, are they useful?
Do they destroy the lines by bulging at all?
And in particular, I remember seeing a kilt that had an under apron pocket that looked uncomfortable to walk with when full. Am I mistaken?

I reckon pockets would be nifty on a kilt but I just cannot see it working. I would probably get a kilt with pockets and never use them.

Thanks for your help
