I am of course perfectly clear that one can not expect a carnival costume compatible for so little money. For this purpose they were not even thought of. But a one-time wear for an afternoon at home was supposed to be in there already. And if they dissolve during the afternoon while playing and running around slowly, then so be it. But the first half hour to welcome guests they should already survive.
Although I am of the opinion that quality must come at a price, so that the achievement of good product well worth, I have to say in this case: Not only manufacturing. I had two boys bought a costume, and none of them has no remedy tightening survived.
We have bridged with minimal technical skills and a needle and thread in the afternoon, but that may not indeed be the intention.
