Is blue jean a character?  Or are you looking for a particular color of clothing item prop? 

Your post is not very clear...

Up at the top right of pretty much any page here you'll find "Search Renderosity" and an area where you can type "blue jean for Poser  5" and hopefully something will come up.

The Search function here works really well after many moons of it not so much!!  Give it a try, perhaps you'll find the wealth of knowledge here that's already been asked, posted what have you!

You are pure, you are snow
We are the useless sluts that they mould
Rock n roll is our epiphany
Culture, alienation, boredom and despair
