I have an idea how to sew original and unique costume! But it will take a lot of time that's why only strong desire would make you sew it :)
The costume in itself is very usual, but it's embroidered by 2006 buttons!!! If there won't be space for all buttons, you can put the rest buttons on a thread and sew these button threads to the costume!
But, no doubt, this costume requires a lot of time, that's why i want to suggest you another costume which is quite simplier... You can sew, or rather embroider some your costume by Christmas tree decorations. Here you are absolutely free to give way to your fantasy! The only advice - don't take heavy and glassy decorations!
Nappy New Year!
