Space suits of astronauts are not "fashionable". From 10 to 12 hours a day the astronauts wear "Penguin" cotton track space suits which are "reinforced" with elastic tape in some places to put an extra load on the muscles and thus compensate for the absence of the force of gravity.
Each member of the space ship crew is also supplied with a vacuum space suit. Its purpose is to cause and additional flow of blood to the lower part of the body. This space suit looks a bit strange on a person wearing it.
Imagine the astronaut wearing the costume looking like a keg around his waist with corrugated trousers with metal shoes extending from the bottom. The top of the keg has a rubber corset which fits tightly round the body. When the air is pumped out of the suit, the lower part of the body will be surrounded by a more rarefied atmosphere than the upper one. The effect has long been known and applied in medicine, for instance, in treatment of colds. Many people have experienced the application of cups.
Prior to descent to the Earth the astronauts wear their vacuum space suits to adjust their cardiovascular system to the Earth's force of gravity.
Each member of the space ship crew also has a space suit for work outside the space orbital station. This is a miniature spacecraft or rather a pressurized module of minimal size. It is fitted with a life support system which provides the wearer with oxygen and removes excess heat.
The life support system is highly sophisticated to enable the cosmonaut to work in conditions of high vacuum, intensive radiation and sharp temperature fluctuations from +150C on the light side of the space station to -150C in the shadow.
When space ships are being inserted into orbit, during docking and reentry, astronauts wear light space suits which are designed to protect them against accidental depressurization.
