Oh my gosh have you flown by the post office today?
They replaced the ballerina set with a 'layered petal' outfit and it's so pretty. It's brand new (though maybe a DS outfit) except for the shoes and headpiece.
must repeat to myself: I'm saving my diamonds, I'm saving my diamonds
Edit:in reply to Olivia below
LOL Olivia, well I guess it works better when buying the outfit pretty much wipes out all your diamonds (I've yet to buy any extra and so am gaining slowly as I level up.)
