Zipper problems, cheap construct

We had similar problems with the zipper that other users have noted - the teeth would no longer close properly after the very first time we zipped/unzipped the costume for my daughter to try it on. I contacted the seller for a replacement, and they apologized and told me they had been previously unaware of the problem but had since heard from multiple buyers experiencing the same zipper malfunction. I was offered a partial refund if I wished to keep the costume and replace the zipper myself or a full refund if I wished to return it. We opted for the partial refund as the zipper was a very simple replacement to make, due to the suit's construct.
