The other reviewer here wrote their review only a few months ago, so I have a hard time believing that the company revamped their sizing system in the time since, so I don't know what happened... I received my Hush Puppies "Imperial" Mary Jane shoes in the mail today, and I am already absolutely in love with them despite some size issues!  I generally wear a size 7.5 shoe but, taking the other reviewer's comments into consideration, I ordered these Mary Janes in a 7.  I honestly think I would be more suited to a 7.5, because although I do fit these shoes, they are a tad snug.  Being leather, though, I assume that with time they will stretch a bit; and I'm not going to return them and order a half-size larger because I purchased them specifically for an event I will be attending soon, and I don't think I have enough time to deal with all that packing-and-shipping-and-waiting rigmarole, and receive the new shoes in time.  Still, even though they're a bit snug in the toe area right now, the shoes are very comfortable otherwise and obviously well-made, and I love the color (I ordered the brown variety).  I think I might actually save up for another pair and order it in my usual 7.5, and just keep them hanging around until this present pair wears out.

**Additional Comments: Today is 7/30/2011 and already my size 7 "Imperial" Mary Janes have stretched enough so that they are very comfortable on my feet.  Great shoes--and I've received lots of compliments on them. :)
