you can pick up a plain dress, and a line one? lighter in colour, back comb your hair a bit- see if you can find a bone to fix in it!! lol!! wear a big chunky pearl necklace, im sure if i remember rightly thats along the right lines??xxx
or nip to a market/shop that sells fabric and get some fake fur (you can get some quite cheap ones) and then cut yourself a one shoulder dress, you can even use safety pins down the side and for the shoulder as the pile is thick and it'll look ok.
Why not go as pebbles. You've got blond hair(put it up), then you just need black shorts and a pink top. Dont forget a white bone for your hair. i guarentee no one would have thought of that!!!
Have fun xoxox
