Abstract: A method of manufacturing an article of clothing includes the steps of providing an article of clothing having a single large size, subjecting the article to a tying process, and subjecting the article of clothing to a shrinking process after the tying process to obtain a tie-shrunk article of clothing having an entirely reduced size with elasticity due to the shrinkage of tie-shrunk article of clothing, so that an entire portion of the single large size article of clothing fits a wearer of any size.
