Collar For Rough Coated Collie

I keep browsing the internet for new dog collars and end up giving up with frustration. I think i've found some to put on a short list for Flynn and Jessie but Jed is my problem.

I'm looking for a nice, fancy collar for him. They only wear plain, cheap collars when out and about because they get wet, muddy, entwined in brambles etc but I want some better collars for when they go to fun dog shows or training class.

Here's the problem...Jed is mainly black and is rough coated so I need a collar that will be visible - I cant even decide on the colour! He currently wears a rolled slip collar which is quite loose so it doesnt damage his fur (not too bothered about that now they get taken off in the house).

Has anybody got any ideas or pictures of what collars their longer haired dogs wear? (Not fond of glitzy collars BTW!)

Thanks in advance.
