One common fashion for women’s suits is the full-length sleeve. This sleeve should fall at the top of the wrist. You can check the length by putting your arms straight out; if the sleeves are above your wrists they are too short.
A three-quarter-length sleeve is common as well for women’s suit jackets. This sleeve should fall between the elbow and the wrist.
The length of the sleeve depends on your fashion preference. A full-length sleeve should come to the top of your wrist while a three-quarter-length sleeve should fall between your elbow and wrist.
