Apr 19, 2021 · A hemline is a line formed by the bottom edge of a garment – and as in anything related to fashion, style and clothing, a hemline is not limited to a single type – As if, if you have seen a straight hemline you have seen it all – What a joke! There are so many other types of hemlines than that straight one.
