As shown as the picture, really nice and for once I had no issue with my bust. The material is stretchy, except for the wrists and neck. It's a bit tight there even though I am size 36 EU and ordered L. The skirt is really short too (I'm 172cm), but nothing shorts cannot fix! If you are ordering the shoes with it, I would recommend going 1 size up as well.
Needlessly to say, the tail is a bad addition, I would not use it, because it takes so long to pump (pump included).. But if you don't have a tail, it could be a cheap alternative.
Overall I think it's a nice costume, but by adding the balloon tail to it, it made the whole picture looks pretty cheap and wish there was an option to not pay for the tail I will not use.
