Outseam refers to the length of the outer side seam on a pair of pants, shorts, or similar garments. It is measured from the top of the waistband to the bottom of the leg opening. For example, on a pair of jeans, the outseam would be the distance from the top edge of the denim waistband down to the hem at the ankle.
Understanding this measurement is beneficial for several reasons. It aids in determining the overall length and fit of a garment, especially when purchasing items online or without trying them on. Historically, tailors have relied on this measurement for accurately altering or creating custom-fitted clothing. Accurate assessment contributes to customer satisfaction and minimizes the need for returns or alterations.
