I ended up building up my British Army loadout for two reasons.
1) I just don't think L85s look as good unless they're coupled with the proper kit.
2) Since I already had the gun, I thought that limiting myself to one avenue of gear - Just British stuff, instead of everything I like the look of - it might save me some pennies because I wouldn't just impulse buy everything I saw.
Turns out I spent just as much, just instead of it being limited by only buying British stuff, I just ended up researching British stuff a lot more and having just as much stuff to pick at... =/
Fail strategy.
What I would advise doing, is making a note of things that could help you out whilst you're playing, and then buying something to fulfil that requirement.
For example, if you're hiding in a bush and you get spotted, you might want some camo to make you harder to see, or if you run out of ammo you might want to buy a pouch to carry a spare mag or two.
You might buy some pyro and realise you have nowhere to actually put it where you can quickly and easily get it, so look for pouches to hold it.
Once you've bought a molle rig of some description and outfitted it with pouches entirely based on what you feel you need, it'll start looking like a pretty legit loadout anyway.
Doesn't have to cost you the world, and it doesn't have to all be bought over night. Just buy what you think will help, work out where best to mount it to yourself, and add to it and move it all around as required.
Practicality comes first if you want to have fun. Trying to tailor your look after a special forces unit will probably see you carrying too much stuff and being too overburdened to really get about effectively or quickly because remember who you're playing against - guys wearing nothing but combats and a t-shirt, with a polymer gun, no rig, and a pair of high caps.
