So I've been to Scotland...a few observations:

It's very rare to encounter casual kiltwearers...pipers, shop staff, Highland games and wedding parties...yes, but don't expect to see many wear their kilt casual.

Apart from P1M and Cessna...seen only 1 (in Inverness)

Sort of weird, because many told me how nice it was to see someone wearing his kilt. Men nodded their head, women smiled, basicly the same as where I live...strange.

Lots of people (read: women) started a chat with me...they where surprised I wasn't Scottish (that's understandable of course), but nobody was offended because of it.
Without exception they liked it and some told it's a shame few Scots wear their kilt.

Many tourist took pictures of me (Royal Mile, Urquhart Castle, Culloden, etc.)....really funny

Conclusion...it's nice to wear a kilt in Scotland, but it's a bit disappointing the kilt is a rare sighting...even in Scotland.

Kiltshops/Kiltmakers:

It's nice to visit kiltshops in Scotland, but some sell trash or just standard gear, poor service, high prices, shockingly little knowledge.

An example...

"I'm looking for Lovat blue hose"
"Lovat Blue what?"
"Hose..."
"Hose?"
"Socks...."
"Ah!...no, we only have white socks"

The "big names" like Geoffrey (Tailor), Kinloch Anderson, Lochcarron and Hector Russell offer good quality and have a well trained staff, but also lots of standard stuff...not much special.
I was looking for a good quality (handmade) daywear sporran...nothing special found, just the standard sporrans we all know. Often cheaper when you buy them through internet shops btw.

Conclusion...I'm spoiled
