What is spongebag trousers?

Spongebag trousers are a type of loose-fitting trousers that were popular during the early 20th century in Europe. They are made from lightweight fabric and have a distinctive baggy appearance, with a high waistband and a pleated front. They were typically worn by men and were often paired with suspenders or braces. The term 'spongebag' refers to the way the trousers billowed out when they were worn, resembling a spongebag. Today, spongebag trousers are more commonly associated with vintage fashion and are often worn as a fashion statement rather than for practical reasons.
