What is your biggest failure?

The most disgraceful time was to buy a sweater from the Internet. It was really beautiful at that time, only a few thousand dollars. It has a unique shape and is very individual. Each button has its own fixed position, not the traditional rules. I was shocked at that time. I answered it right away. After I bought it, I tried it on The effect is good, very handsome and unique. It shrunk after washing.
