jersey help please...

I ve been creating a jersey today for some patch , but suddenly i realised the white was an easy jersey but i couldn't make the black , have a look


That's the white i made .

Whenever i draw it black and make it multiply or overlay i can't seem to see the details of the jersey ....
Any help?
I'm new in jersey making im good in cyberfaces .
