I want to invent a dress that can change style at any time, in the cold place, it can become a warm cotton wool, in the hot place it can become a short sleeve, when I want to attend the meeting, it can become a decent suit, when I want to go to the dance, it can become a gorgeous dress, it is working through nanotechnology, for people to buy this dress is equivalent to buying a lot of clothes, so I think it should be 100,000 yuan to buy
