craftgrrl | Hoodies and Costumes

I'm taking a Garment Structures course at my school (www.cca.edu) this summer and I'm interested in making a hooded sweatshirt with a zipper and ears and a tail and all that. I've purchased some old stuffed animal patterns on eBay to teach me how to make ears and tails and things, but I haven't run across a decent pattern for a zippered hoodie yet. Does anyone have any suggestions for zippered hoodie patterns that I could buy or find online?

I'm also interested in making animal/monster costumes and I've gotten some really basic costume patterns, but none of them are as advanced as I'd like. I'd like to make something that involves a certain amount of upholstery/foam padding since I'm also taking an upholstery course. I've only been able to find very simple all-cloth costumes so far so I'm starting to think that if I want to do anything more complicated I'll have to design it myself, but I thought I'd see if any of you had any ideas.
