I'm really happy with the quality and appearance of the costume. I think it is definitely convention worthy. However, I got a small because my dress size is a 4, and it fits me well everywhere except the sleeves and the legs, they are way too short (I have a 34' inseam and long arms) so it would be nice if the company would provide some more measurements than just dress size because it's not a dres...and I was worried that the Medium would be way too big and not fitted, but for this halloween I'm going to just wear some inconspicious black pants which will accomodate my shoes as well, because the legs close fitting all the way down like leggings and are too skinny for most shoe types.
