Answer 2

As of my last knowledge update in September 2021, there is no specific information available about a designer creating a "jarket." It's possible that you meant to type "jacket," in which case there are countless designers and brands that produce jackets using various materials, styles, and techniques. Designers may use a wide range of materials such as leather, denim, wool, polyester, and more to make jackets.

If you have a specific designer or brand in mind, please provide their name, and I might be able to offer more relevant information. Otherwise, if you have any other questions or need assistance with anything else, feel free to ask!
