I do like the idea of wearing a TOS with a kilt, but for me it is not suitable for formal wear, I do like it a lot for casual wear with a kilt. A TOS was my most used headdress while serving, (working and combat dress).

I find it very suitable for hiking. I have to say though I am not impressed with the latest issued TOS in the British Army. It looked to much like a beret!

It has to khaki! 😊

Whatever you feel the most comfortable with and as long as it is not too extreme.
