armhole

Ever wonder exactly where the body of your shirt ends and the sleeve begins? That boundary is defined by the *armhole*! It is the specific opening in a garment—like a shirt, dress, or jacket—through which you put your arm.

Think of it as the crucial curved opening (and seamline) that allows for movement. In a T-shirt, the sleeve is sewn into the armhole. In a sleeveless vest or tank top, the armhole is simply the finished edge that frames your shoulder and underarm area. If a shirt feels tight under your arm when you reach forward, the armhole is likely cut too high or too small!

An armhole is the curved opening in the bodice of a garment designed for the arm to pass through. It is a fundamental part of clothing construction, found in everything from casual tees to tailored coats. While it might seem like just a simple hole, the shape and size of an armhole significantly impact both comfort and style.

In the world of tailoring, the armhole curve is often called the armscye. Designers must calculate and cut this curve carefully; if the armhole is cut too low, lifting your arm can pull the entire garment up and out of place. If it is cut too high, it can rub against the skin in the armpit.

So, whether you are admiring the cut of a bespoke suit or simply pulling on a comfortable sweater, the armhole plays an essential role in how your clothes fit. It isn't just an empty space; it is the anchor point that connects the sleeve to the body of the garment, ensuring you have the freedom to move.
