A scam.
The video advertising the sweater showed a presumably American guy hand-crocheting butterfly sweaters, while being ridiculed for making them. I was shocked to find that it was being shipped from Slovenia! Another surprise was that it is machine knitted, not hand crocheted. It's beautiful, but not what I thought I bought. Really wanted it to be hand crocheted. AND! My $79 purchase ended up costing $107, probably because of customs issues from Slovenia. What a scam.
