Hey I was thinking about buying one of those jackets. I was thinking about getting one off ebay cause everywhere else like in stores they are over $100 and they're alot cheaper online. But I was wondering if anyone here knew a few things...ok...I found one I like alot but it has a hood on it and I probably wouldn't wear the hood. I know you can take the hoods off some of them, but can you take it off all of them? And also I think I'd need a small. I'm pretty little...would I need a petite small? how do they fit? or would just a regular small be ok?
