What is the term for a shirt design where the bottom is shorter at the seams and longer in the center?

The term for a shirt design where the bottom hem is shorter at the seams and longer in the center is called a "shirttail bottom." This design typically creates a visually appealing shape and allows for a more comfortable fit, accommodating dynamic movement while also enhancing the drape of the garment. The shirttail bottom is often seen in casual shirts and can add a stylish flair, as it helps the shirt stay tucked in or drape nicely when worn untucked.

While other terms might describe different shirt shapes, "shirttail bottom" specifically highlights the distinct curvature that provides practical benefits and aesthetic appeal. This design is particularly popular in various styles, such as button-up shirts, to maintain a polished yet relaxed look.
