Ask a brand how long a production order takes, and the answer is usually "however many days the factory quoted for production." Ask a factory the same question, and the honest answer includes several stages that happen before a single unit is cut. Understanding the full timeline — not just the production window — is what makes a launch date realistic instead of hopeful.
Sampling: 2 to 4 weeks, often more
Proto, fit, and pre-production samples each involve making the piece, shipping or reviewing it, and waiting for approval or revision notes. A single round of changes on any of the three can add a week by itself. Brands that budget one week for "sampling" almost always end up compressing something else later to make up the difference.
Material sourcing: can run in parallel, but only if planned early
Fabric and trims are often ordered once the fit sample is approved, since fabric consumption depends on the final pattern. Standard, in-stock fabrics can be ready in days; custom colors, prints, or specialty fabrics can take three to six weeks on their own. This is the stage most likely to become the hidden bottleneck, because it happens out of sight while everyone is focused on the sewing floor.
Bulk production: the part that gets quoted, but isn't the whole story
This is the number most factories give when asked "how long," and it is usually accurate for what it covers — cutting, sewing, and in-line quality checks. For a mid-size order, this typically runs two to four weeks depending on garment complexity and order volume, but it only starts once materials have actually arrived at the factory.
Final inspection and packing: a few days, but non-negotiable
Final QC, folding, tagging, and export packing typically take three to seven days. Skipping or shortening this stage to hit a deadline is one of the more common causes of a shipment that leaves on time but arrives with problems that final inspection would have caught.
Shipping: the part brands most often underestimate
Ocean freight from China typically runs two to six weeks depending on destination, plus customs clearance time on the receiving end. Air freight cuts this to days but at a much higher cost per unit. A launch date set from the factory's "ready date," without adding transit time, is the single most common reason a product misses its intended launch window.
Adding it up: from a confirmed design to product in a warehouse, eight to fourteen weeks is a realistic range for most orders — sampling included, worst-case delays not included. Brands that plan backward from a real launch date, using this full breakdown instead of just the production quote, are far less likely to be surprised.
