6?1 What is the most expensive brand of clothes in the world?

The most expensive clothing in the world - the clothing of American astronauts. Each set is worth $9 million! The space environment is extremely harsh. In addition to microgravity, there are also high vacuum, lack of oxygen, extreme temperature changes, terrible cosmic radiation, and a large amount of micrometeor dust, which will cause fatal harm to the human body. Therefore, astronauts must wear spacesuits once they leave the spacecraft for extravehicular activities. The function of the space suit is to maintain atmospheric pressure, provide oxygen, discharge carbon dioxide, prevent cosmic radiation, heat insulation, and prevent micro-meteor dust. The purpose is to ensure the safety of astronauts in space. This kind of clothing for astronauts to walk in space is called an extravehicular activity spacesuit. The extravehicular activity spacesuit is the most complex, technologically advanced and most expensive garment in the world. The space suit consists of clothing, helmet, gloves and space boots.
