I wore these a few times after purchasing them as deadstock at a vintage clothing store. Action Slacks were a line of stretch polyester slacks developed by Levi's from the 1980s to the early 2000s that took the world by storm. As a successor to STA-PREST, they are a masterpiece of business casual, characterized by their comfort, beautiful silhouette, and resistance to washing, all without the need for ironing. They have an exquisite silhouette that is neither too baggy nor too tight, with a center crease that gives them a neat impression. Many styles also feature a slight flare towards the hem, which can make the legs look beautiful. While many slacks are made of wool and can be a bit troublesome to wash, Action Slacks are made of polyester, can be washed, and their center creases don't disappear, making them a versatile "pseudo-slacks." They fit me perfectly at 172cm.
