I have never made any sort of cosplay before, so anything at all would be helpful. It can be as broad or as specific as you have.
Go to images.google.com and search "hoodie pattern". You can adjust the pattern to anything you want. Get advice at the local fabric store, probably Jo-Ann's.
You can also search for "Virgil Sanders hoodie" but the results do not look useful. They make me wonder why anybody would want to look like that.
