Custom Overalls Manufacturer: Fabrics, Hardware and MOQ

Custom overalls manufacturer programs usually use 10–14 oz denim or duck canvas (about 340–475 GSM), with adjustable straps, metal buckles and bar-tacked stress points. Many factories start at 100–300 pcs per style and colour, take 10–18 days per sample round and deliver bulk in about 35–50 days after approval.

Overalls have moved from the farm and the workshop into streetwear and womenswear, and they still sell to trades buyers who need tough, practical garments. That spread creates opportunity, but it also means the word "overalls" covers very different products. A heavy canvas work bib and a soft washed fashion dungaree share a silhouette and little else. This guide works through overalls construction as a checklist and highlights the fit decisions that matter most.

What is a custom overalls manufacturer?

A custom overalls manufacturer is a factory that produces bib overalls, dungarees or coveralls to a brand's own pattern, fabric, hardware and branding, for workwear, streetwear or fashion collections. Most programs use 10–14 oz denim or duck canvas (about 340–475 GSM), start at 100–300 pcs per style and colour, and need about 35–50 days of bulk production after a sample is approved.

Checklist part 1: Fabric

Start with the job the overalls must do:

• Workwear: duck canvas or heavy denim, often with a rigid hand and high abrasion resistance.
• Streetwear: washed denim, garment-dyed canvas or corduroy for a softer look.
• Womenswear: lighter twill or stretch denim with a closer fit.

Ask for fabric weight, composition and shrinkage data. If the garments will be garment-dyed or washed, test the fabric through that process first. Our how to choose fabric weight for a clothing brand guide explains how weight affects drape and price.

Checklist part 2: Bib, straps and hardware

The bib and straps carry the garment. Check:

• Bib height and width, and whether the bib has a pocket or a zip chest pocket.
• Strap width and the type of buckle or slide.
• Side openings with buttons for easy wear.
• Hardware finish and rust resistance.

Hardware is often supplied by specialist trim makers with their own minimums. Confirm the finish and quantity before sampling.

Checklist part 3: Reinforcement and pockets

Stress points need bar tacks or rivets: pocket corners, strap joins, fly and crotch. Workwear overalls often add double knees, hammer loops, tool pockets and triple-needle seams. Fashion overalls may simplify pockets to keep the line clean. Decide which features are essential for your customer, because every extra pocket adds cost and sewing time.

Workwear vs fashion overalls: which option fits?

Use this table to position your product before writing the tech pack.

The trade-offs are durability and function versus comfort and style. Many brands launch one heritage workwear style and one fashion version that share hardware to simplify sourcing.

How should overalls fit across sizes?

Overalls are harder to size than pants because they depend on torso length as well as waist and inseam. A good size chart covers waist, hip, front rise, back rise, bib height, strap length and inseam. Adjustable straps solve part of the problem. Run a fit session on at least two body types, and check sitting and bending, not only standing. Our how to create a size chart for a clothing brand guide shows how to build the chart.

How do you control washing and colour?

Washed overalls must be sampled after washing, because canvas and denim shrink and twist. Approve a wash standard and keep a physical reference. Garment-dyed styles should have a colour standard for each colourway. Check that hardware survives the wash process without discolouring the fabric.

What should you budget for?

Overalls use more fabric than pants, plus hardware and extra sewing time. Key cost drivers are fabric weight, the number of pockets and reinforcements, hardware type and washing. To compare quotes fairly, send the same tech pack to each factory and ask for a breakdown. Our apparel manufacturing cost and pricing hub explains how to read quotes.

How do coveralls differ from bib overalls?

Coveralls, sometimes called boiler suits, cover the arms and torso as well as the legs, with a front zip or buttons. They are common in mechanical, industrial and some fashion collections. Coveralls need a full-body pattern, sleeve and shoulder fitting and a longer front opening, so they take more fabric and more sewing time than bib overalls. Grading is also more sensitive because the garment must fit the body from shoulder to ankle. If you plan both products, develop the bib overall first, then reuse the leg block and fabric for the coverall to save sampling time. Some industrial buyers also need flame-resistant or high-visibility versions, which add certified fabrics and testing to the plan.

How do you plan a first overalls order?

A sensible first order is one style in two colours, for example a rinse denim and a natural or brown duck canvas, across five sizes. Keep hardware consistent across both colours to meet trim minimums. Ask the factory for a pre-production sample in each colour, and check the strap hardware, side buttons and bar tacks before approving. After the first sell-through, extend into a cropped fashion version, a kids version or a lined winter version, reusing the approved fabric and hardware where possible.

What questions should you ask an overalls factory?

• Which overalls or workwear brands have you produced for?
• Do you have in-house washing, or do you use a partner laundry?
• Where do you source buckles and slides, and what are the minimums?
• How many bar tacks do you place and where?
• What seam strength or abrasion tests can you arrange?

How should overalls be packed and labelled?

Overalls are bulky, so agree on folding and polybag size early to control carton count and freight cost. Fold straps inside the bib so buckles do not mark the fabric, and add tissue or a card if hardware might scratch. Include fibre content, care, country of origin and size labels, plus any hang tags that explain fabric weight or workwear features to retail buyers.

Common mistakes with overalls

• Using a pants pattern and adding a bib without checking torso length.
• Choosing hardware that rusts or marks the fabric after washing.
• Missing bar tacks at strap joins and pocket corners.
• Approving an unwashed sample for a washed bulk order.
• Offering too many sizes in the first run.
