What's the name of a dress with a hole in the sleeve for wearing a thumb?

This cuff detail is called "ninja buckle", which is very similar to the Japanese ninja cuff equipment. As for what brand to sell, it's hard to say. This is not a patent. However, I know that this is the cuff of POLO RALPH LAUREN RLX down jacket that Taobao sells well this year. As for the down jacket itself, there are good and bad, imitation goods are flying all over the sky, and the general asking price is about 700.
