Costume rather cheap, return shipping you must take over

My costume arrived on time, until then everything was super.
The tulle skirt was very bulky and has not looked beautiful. At the abdomen is black velvet, which sat very loose (even though I have the smallest size S ordered) and also did not look very nice.
The feathers on the breast are beautiful, and they do not sit in the correct position.
When I decided to return it, I was only told that I have to accept the return costs yourself (4.90), over whom I have annoyed me a bit.
