Props people buy off corners! A fellow designer friend of mine worked for Will and Grace and she bought fake jewelry, bags, etc from flea markets and off of corners all the time. Sometimes they got promo things from different designers but (and especially when a show is brand new) they have a strict budget.
I noticed this when it was on tv but chose to ignore it, i was like "No! I thought that Suhalili was real the other week but now the polly has a front pocket? AHh!
The funny thing I notice is, that a lot of the faked stuff has more practical features, like zippers on a bucket, feet on a speedy, and pocket on a polly. I wish that the real ones had those. (especially zipped bucket, yummy)
