What is an Armscye?

An Armscye typically refers to the outline of the armhole in the field of tailoring to construct specific patterns specifically.

It’s basically the armhole opening in apparel through which the hand, and then the arm passes easily, and then lastly a sleeve can be joined to it.

An armscye length is determined by the total length of armhole measurement to the edge where the sleeve is joined.

The width is measured by taking account of the distance across the hole at the widest point.

An Armscye is mainly at the opening of the bodice, at the place where the sleeve is attached. The correct adjustment of an armscye is crucial to do pattern shape.

As the right cutting of an armscye leads to improved comfort and better movement. In case, if you are shorter or taller than normal then the need is to adjust your armscye.

When you feel the shirt is too tight or too loose like having creases on the material near your armpit, then it’s a sign that may require adjusting your armscye.

For example- the accurate cutting of an armscye is a key element to any jacket or coat.

Hence careful attention is given to the size and height of the armscye.

Why is it Called an Armscye?

Armscye can be also pronounced ‘Arm’s Eye’ is originally a Scottish term. Earlier the expression “arm’s eye” was used in older sewing texts.

It’s also predicted in earlier records that the apostrophe and the crossbar of the lower case “e” were unclear.

The neologism “armscye” was generated by readers, who omitted the sound of orphaned fragments “arm” and “s” with the corrupt “cye”.

In the 20th century, writers found the original term more logical.

However, as self-proclaimed experts copied each other, the term “armscye” eventually prevailed and was commonly used by local tailors to gain general acceptance.

How is Armscye Measured?

The Armscye measurement is taken from the tip of the shoulder, then around the edge of the bust, under the arm, and back up to the shoulder.
