How early should a streetwear brand book jacket production capacity?

A streetwear brand should discuss jacket production capacity as early as possible, especially for varsity jackets, bomber jackets, work jackets, denim jackets, puffers, windbreakers, and racing jackets. Custom jackets usually require more production steps than T-shirts or simple hoodies. They may involve shell fabric, lining, rib, zipper, snap buttons, embroidery, patches, quilting, washing, or special packing. If the brand waits until the sample is fully approved before discussing capacity, the factory line may already be booked. Mature brands usually share estimated quantity, target delivery date, fabric type, artwork complexity, and reorder possibility early so the manufacturer can prepare production planning more accurately.
