Suit quality control checklist for wholesale buyers

What should a suit quality check cover?

A suit quality check should cover fabric, construction, fit and measurements, finishing, labels and packing, inspected on a random sample of the order. Problems with suits are rarely one big fault. They are usually small issues, like shading between jacket and trousers or a lapel that does not roll, that add up to returns.

At our factory, quality control runs at every step, from fabric inspection to final pressing, under an ISO 9001 certified system. Many buyers still want their own check before shipment, and we support that. This checklist is what we recommend buyers use, whether they inspect themselves or hire an inspection company.

Fabric checklist

Check the fabric first, because fabric faults cannot be fixed by sewing. Look at each garment under good daylight or a daylight lamp.

• Colour matches the approved sample or swatch
• No shading between jacket, trousers and waistcoat of the same suit
• No shading between suits in the same colour lot
• No weaving faults: slubs, broken yarns, holes, thick or thin lines
• No stains, oil marks or chalk marks left from cutting
• Pattern (check, stripe, jacquard) matched at front, pockets, back seam and collar
• Fabric composition matches the order and the care label
• Hand feel and weight consistent with the approved sample

Shading is one of the most common complaints in suiting. It happens when panels are cut from different fabric rolls. Ask your supplier how they control it. The usual method is to cut all parts of one suit from the same roll and keep jacket and trousers together through production.

Construction checklist

Check seams, buttonholes and the jacket's structure. These decide how long the suit lasts.

• Seams straight, flat and even, with no puckering
• Stitch density consistent, no skipped or broken stitches
• Loose threads trimmed inside and out
• Buttonholes cleanly cut and fully stitched, no fraying
• Buttons sewn firmly, with a thread shank on jacket buttons
• Pockets symmetrical, flaps lying flat, pocket bags secure
• Lining sits flat, with enough ease so it does not pull the shell
• Vents hang closed and straight
• Trouser fly, zip and waistband closure work smoothly
• For ceremony styles: rhinestones, sequins and embroidery secure, with no missing stones

Fit and shape checklist

Put the jacket on a dummy in the right size and look at it from the front, side and back. Fit faults are easier to see on a form than on a table.

• Lapels roll smoothly and lie flat, with no bubbling
• Both lapels the same width and shape
• Collar sits close to the neck, with no gap at the back
• Shoulders smooth, no dimples or wrinkles at the sleeve head
• Sleeves hang straight without twisting
• Left and right fronts symmetrical, pockets at the same height
• Jacket closes without pulling at the button
• Trouser creases centred and straight

Measurement checklist and tolerances

Measure each sample piece against the size spec and accept it only within the agreed tolerance. Agree on tolerances in writing before production, not after.

These are common starting points in suit production. Your brand may set tighter or looser numbers. The important thing is that both sides use the same spec sheet and the same way of measuring. Our size runs and lot planning guide explains how sizes and drops relate.

Finishing, labels and packing checklist

Check the last steps, because this is what your customer sees first.

• Pressing clean, no shine marks, no creases in the wrong places
• Main label, size label and care label correct and sewn straight
• Size on the label matches the actual measurements
• Composition and care instructions correct for your market
• Hang tags and barcodes correct, if ordered
• Each suit on the right hanger, in a garment bag or polybag as agreed
• Jacket and trousers of the same size packed together
• Carton contents match the packing list: model, colour, size, quantity
• Carton marks correct and cartons strong enough for the shipping method

For private label orders, check your branding on every point: neck label, lining, buttons, hangers and garment bags. Our private label suits page explains what can be customised.

What is AQL, and which level should I use for suits?

AQL (Acceptable Quality Level) is a sampling method that tells you how many pieces to check and how many defective pieces you can accept before rejecting the lot. It comes from the ISO 2859-1 and ANSI Z1.4 standards. For apparel, the common setting is General Inspection Level II with AQL 2.5 for major defects and AQL 4.0 for minor defects. Critical defects, such as a needle or sharp object left in a garment, are usually set at zero.

Here is how it works for single sampling under General Level II, AQL 2.5:

AQL counts defective garments, not single defects. A suit with two faults counts as one defective unit. The inspector picks the sample at random from all sizes and colours, so the check represents the whole order.

Defects are usually sorted into three classes:

• Critical: a risk to safety or a legal problem. Example: a broken needle in the garment, wrong composition label.
• Major: likely to cause a return. Example: visible shading, a broken seam, measurement outside tolerance, a missing button.
• Minor: unlikely to cause a return. Example: a short loose thread, a small pressing mark that can be fixed.

When should a pre-shipment inspection happen?

A pre-shipment inspection happens when production is complete and most of the order is packed, usually a few days before the goods leave the factory. That way the inspector sees finished, packed garments, and any problem can still be fixed before shipping.

For large or first-time orders, some buyers also ask for an inline check during production. This catches problems early, while there is still time to correct them across the rest of the order.

Can I use a third-party inspection company?

Yes. You can send your own team or hire an independent inspection company to check your order at our factory in Istanbul. Share your spec sheet, tolerances, approved sample and AQL level with the inspector before the visit. We prepare the goods and give the inspector space and access to the cartons. Many buyers do this for their first orders and then reduce inspections once they trust the results.
