What is a "grandad shirt"?

A grandad shirt, also known as a grandfather shirt, is a type of shirt that has a collarless design and a button-up front. It is characterized by its relaxed fit and comfortable fabric, which often includes cotton, linen, or a blend of both. The grandad shirt gets its name from its resemblance to the type of shirt that grandfathers or elderly men might wear, particularly in Ireland and other parts of Europe. It has become a popular fashion choice for both men and women due to its versatility and timeless style, and is often worn for casual occasions or as part of a more laid-back outfit.
