In order...

Shirt - Usually a t-shirt or polo.
Kilt/Cilt - I wear my UK's more than my Tartan(s).
Belt - I always wear a belt.
Socks/Hose - Depends on the weather and where I'm going.
Boots/Runners - Also depends on where I'm going.
Sporran - Almost always, even with my UK's, just not around the house.
Kilt/Cilt Pin - Only with Tartan.
Jacket - Depends on the weather and where I'm going.
Hat - If I feel like wearing one.
Misc -As for a knife, I don't own a Sgian dubh (yet), but I sometimes keep a pocket knife in my Sporran.

Then I look in the mirror to make sure I look as good as I feel.
