L/S stands for long sleeve, a standard notation used on tech packs, line sheets, and clothing labels to specify garment construction. Designers and buyers use this abbreviation to quickly distinguish between sleeve lengths in a collection, especially when a single style is offered in multiple variations. The notation ensures clear communication across the supply chain, from the pattern maker drafting the sloper to the warehouse worker picking the final inventory.
Heard on the job
Check the line sheet to see if the ribbed henley is available in L/S or just short sleeve.
Insider tip
You will often see this paired with S/S for short sleeve on inventory lists, but do not confuse S/S with the identical abbreviation for the spring/summer fashion season.
