Uh-Oh ... you are all making way too much sense here and have me worried that SA won't even make Final 2 ? ! I really hope he wins.
As to why Mila was selected over Jay, I was thinking they wanted to appeal to 3 different demographic buyer groups, and Mila's would appeal to the more mature buyer ... and mature figured. Jay's designs would appeal to many who would also like SA's (younger and thinner ), so maybe they want SA to win ?
