1. NASA’s Mercury spacesuits
A no-brainer choice—this is exactly what a spacesuit is supposed to look like. The Mark IV suits were actually borrowed from U.S. Navy pilots, who wore the outfits during high-altitude flights. NASA made some adjustments to the pressure suit, such as adding the aluminum-coated nylon outer shell for improved thermal control, special gloves to allow for finer finger control, and new straps and zippers to ensure a tighter fit. The suit was worn throughout the Mercury era and was later replaced by the Gemini suit in the mid-1960s. To infinity and beyond!
