I formed a large group of cosplayers for Katsucon 2008 in Washington D.C. (an anime/video game convention), and everyone is designed their own costumes based on My Little Pony characters from the 80's cartoon series! I am made Quackers. A reference picture to the pony can be found here
Basically, the tail was made of various marabou boas! Sort of like one of those show girl tails! I decided to go with the duck on the back of the jacket rather than on my butt, but The train is detachable from the pink corset
So yeah, the pink thing is a strapless corset, and the top part is a separate jacket peice. I changed the hot pants to white in my actual costume, thigh-high leg warmers..and detacable back train.
(yes I know my drawing isn't the bestest. I can only draw in 2-D! hahaaa)
