When I was in the Army all of my uniforms were tailored
- lucky you... ;)

Navy surge dress (No 1's - winter) was some of the itchiest material made by man...would of loved to get it made in some other material.

given that we have to buy our uniforms.
Really, in the UK forces..?

Never had to worry about that, given the clothing allowance, and or supplementary "Make a Mend" allowance for uniform ruined / soiled in the process of duty. (One for One)
