First ,You need to read sizes carefully .chinese sizes ( where this comes from ) are much smaller than US or EU sizes ,I read the sizes and got the perfect dress.
It is very well made ,abit surprising ,I thought that am going to recieve a cheap made dress of bad material ,this is exactly the opposite ,It is made from a gorgeous  shiny PVC like material from the outside ,oh,so it is going to be hard to wear is it sticks around??no way,the inner maerial is soft polyester ,this dress is not made of wet look cheap spandex material that gets torn or abraised after few uses ,it is made of the real deal PVC ,Shiny and smooth .
Cleaning : If you are not going to wear it alot ,just polish the out side with a leather )or even glass) spray polish ,otherwise cold water wash ,then polish.
now.why 4 stars after all those good words:
It is because the string openings ( the buckles) are abit loose ,if you tightened the string (to get the shiny wrinckle free look of the dress that it deserves) ,you might get them out of place ,not abig deal though ,you can return them with few stiches with a nylon thread.
Also the string itself is abit cheap ,and stands out from the rest of the dress.
Highly recommended if you can find the right size ,again,you need to check sizes carefully.
