Q&A:

Why is there a long back hem on polo shirts?

The uneven vented hem is a detail that can be traced back in history to the turn of the last century when it was required equipment. Whether you were atop a pony or on the tennis court, the uneven vented hem, often called a tennis tail, served to keep the shirt tucked in as you bend at the waist. The longer back hem also serves to create the illusion of height on the wearer.
