Here is the black kit I use for work in the private security industry
My smock is a webtex copy of a SAS smock in ripstop fabric with knited cuffs and no ziped pockets in the chest or radio loops I have replaced the draw cord with an elastic one and a press stud at the bottom of the zip and a couple of pockets to the upper sleeves
The shirts are ACU copys made by Mil-tec I found the chest pocket too small so I had them replaced with some larger ones and an epulatte ala PCS, The pockets for padding has been removed from the lower sleeves as has the pen pocket from the left lower sleeve, the upper sleeve pockets have been left in place. The trousers are the standard MOD Plod version with an internal batton pocket on the right side, the creases in the front and back of the legs have been permantly sewn in cos Im lazy and do'nt like iorning. One thing I do about every 5 or 6 months is run them throgh the washing machine with a couple of packets of black dye as they tend to fade out when used and washed regularly.
