[Two to 4 inches of positive ease](http://www.ravelry.com/patterns/library/tea-with-jam-and-bread) this has a sweatshirty feel to me.

[Either no ease or a tiny bit of negative ease](http://www.ravelry.com/patterns/library/owls-9)

[calls for 4 to 9 inches of positive ease](http://www.ravelry.com/patterns/library/take-it-from-the-top-602) The one in red looks to be 8 or 9 inches of positive ease and would be a bit too oversized for my tastes.  I like 3 or 4 inches of positive ease--- loose and comfy, can be a layering piece, but not so baggy that I wouldn't go out in public in it.
