Rise
The distance on a pair of pants from the crotch seam to the top of the waistband, at the front or the back.

Sister size
A bra size with the same cup volume on a different band: one band down and one cup up, or one band up and one cup down.

Sleeve length
The length of the arm or sleeve, from the shoulder point (or the center back of the neck, on dress shirts) to the wrist.

Tolerance
The margin allowed between a measurement on a garment's spec or size chart and the same measurement on the garment actually made.

U

Underbust
The distance around the ribcage, just under the bust, measured snugly.
