Why do they call it uniform

[debeau]

Here in New Zealand we have blue shirts wth dark blue piping around the collar and sleeves and of course navy pants .
Due to a sponsor fo some UMPS ( They fully kitted out all our ISF Umps , 12 of them )
we changed to a lighter blue shirt . As shirts wear out we buy the new ones .
Now we have umps with different coloured shirts .
Also with different tournaments we get dark blue or black ,even white shirts and unfortunatly these are starting to be worn in normal week games or national tournaments .
Looks very messy .
Whats worse we dont get paid so if we have to get new gear its all on us .
