What to Prepare Before Contacting a Custom Clothing Manufacturer

Factories are often asked to provide a quotation based on a single product photo.

It may seem like the fastest way to begin, but it usually creates more questions than answers.

What fabric should be used? What should the garment weigh? Is the fit slim, regular or oversized? How many colors and sizes are required? Does the customer need printing, embroidery or custom labels? Is the reference photo showing an exact requirement or only general inspiration?

Without this information, any quotation can only be an estimate.

A professional custom clothing manufacturer can help refine a product, but the more clearly a brand explains its objectives, the more accurately the factory can evaluate materials, sampling, cost, MOQ and production time.

You do not need to have every technical answer before contacting a manufacturer. You should, however, understand what has already been decided, what remains open and where you need the factory’s professional support.

1. Begin with a Clear Product Brief

Before discussing technical details, explain what you are trying to create.

A useful product brief should introduce:

The product category

The target customer

The intended market

The brand’s aesthetic

The expected quality level

The target retail positioning

The planned sales channel

The expected launch period

Relevant reference brands or products

For example, “We need a custom hoodie” is too broad.

A more useful brief might explain that the product is a heavyweight oversized hoodie for a premium American loungewear brand, designed for autumn and winter, with a minimalist appearance and a specific target retail price.

That information immediately gives the manufacturer a clearer understanding of the expected fabric, silhouette, construction, finishing and cost range.

2. Understand Your Current Development Stage

Not every brand contacts a manufacturer at the same stage.

Some customers have only an initial idea. Others have sketches, reference garments or complete technical packs.

Before contacting a factory, determine which of the following situations best describes your project.

Concept Stage

You understand the product and target customer but need support with design, materials and technical development.

This type of project usually requires an ODM or collaborative development service.

Design Stage

You have sketches, inspiration images or reference garments, but the measurements, construction and materials have not been finalized.

The manufacturer may need to help translate these visual ideas into a sample-ready specification.

Production-Ready Stage

You already have a complete tech pack, measurement chart, bill of materials, artwork files and approved construction requirements.

In this case, the factory can begin evaluating sourcing, sampling, pricing and production feasibility more directly.

AOGU supports all three stages through OEM, ODM and collaborative product development.

3. Prepare a Tech Pack—or Clearly Identify What Is Missing

A tech pack is the technical blueprint of a garment.

A well-prepared apparel tech pack may include:

Front and back technical drawings

Additional side or detail views

Measurement specifications

Size grading requirements

Fabric composition and weight

Color references

Stitching and construction details

Print or embroidery artwork

Logo measurements and placement

Label and trim requirements

Packing instructions

Revision dates and comments

The objective is not to make the document look complicated. It is to communicate the product in a way that reduces assumptions.

If your tech pack is incomplete, mark undecided areas clearly:

Factory recommendation required

Fabric to be confirmed

Construction to be tested in sampling

Color under development

Measurement to be adjusted after fitting

This tells the manufacturer where its input is needed.

AOGU can also work from sketches, reference products and initial concepts when a customer does not yet have a complete tech pack.

4. Describe the Fabric by Performance, Not Only Composition

Saying “100% cotton” does not fully define a fabric.

Two cotton fabrics can have the same composition and weight but feel and perform very differently.

Before sampling, consider:

Fabric composition

Approximate GSM

Knitted or woven construction

Surface texture

Brushed or unbrushed interior

Stretch and recovery

Softness and drape

Shrinkage expectations

Breathability

Colorfastness

Wash performance

Certification requirements

If you do not know the exact fabric specification, describe the desired result.

For example:

Heavy but not stiff

Soft brushed interior

Structured oversized silhouette

Four-way stretch with strong recovery

Breathable for yoga and training

Smooth surface suitable for embroidery

A professional manufacturer can use these descriptions to recommend suitable materials and send fabric swatches for approval.

At AOGU, customers confirm the fabric and color before the material is used to develop the final approved sample.

5. Estimate Quantities, Colors and Size Distribution

A factory cannot properly evaluate an order without understanding the intended quantity.

Prepare an estimate covering:

Number of styles

Number of colors per style

Quantity per color

Required size range

Approximate size distribution

First-order quantity

Expected reorder potential

MOQ may be calculated per style, per color or according to the fabric and customization process.

AOGU’s typical MOQ starts from approximately 100 pieces per color per style, depending on the product, fabric and manufacturing requirements.

Brands should also consider how multiple colors affect inventory.

Launching one style in five colors may appear attractive, but it increases the total units, sampling requirements, material commitments and stock risk. A smaller, more focused first collection can sometimes provide better market feedback.

6. Share a Realistic Budget or Target Price

Many brands are reluctant to discuss budget because they worry it will weaken their negotiating position.

In practice, a realistic target helps the manufacturer recommend appropriate materials and construction.

A premium 500 GSM hoodie with specialized washing, custom-developed fabric and complex embroidery cannot be evaluated against the same budget as a lightweight basic sweatshirt.

Useful commercial information includes:

Target manufacturing cost

Target retail price

Expected wholesale price

Required packaging level

Preferred shipping method

Market positioning

The objective is not to reduce quality automatically. It is to determine how the product can achieve the desired value within a commercially workable structure.

7. Provide Reference Products and Fit Direction

A physical reference garment can communicate details that are difficult to explain through photographs.

It may help the manufacturer understand:

Desired fit

Garment length

Shoulder position

Sleeve volume

Hood shape

Fabric hand feel

Pocket construction

Rib tension

Stitching quality

Overall product weight

Explain what you like and dislike about the reference.

A factory should not assume that every element of the sample is correct. Perhaps you like the fabric but not the fit, or the silhouette but not the construction.

Clear comments make reference garments more useful during development.

8. Confirm Branding and Customization Requirements

Branding affects sampling, price and lead time.

Before requesting a quotation, consider whether the garment requires:

Screen printing

Digital printing

Puff printing

Embroidery

Appliqué

Silicone or rubber logos

Woven labels

Printed care labels

Hangtags

Custom drawcords

Branded zippers

Custom packaging

Provide artwork in an appropriate format whenever possible, together with the required dimensions, colors and placement.

The manufacturer should also know whether branding details must match an existing product or whether recommendations are welcome.

9. Build a Realistic Development and Production Timeline

Apparel manufacturing includes more than sewing time.

A realistic schedule may need to allow for:

1.Product review

2.Fabric and trim sourcing

3.Pattern development

4.Initial sampling

5.Customer evaluation

6.Sample revisions

7.Final sample approval

8.Material preparation

9.Bulk production

10.Final inspection

11.Packing and shipping

AOGU’s sampling process may take approximately one week for suitable projects after the required information and materials are confirmed. Bulk production is generally planned around approximately 30 working days following approvals, depending on order complexity, material availability and production scheduling.

Brands should work backward from the required delivery date and include time for revisions, inspection and transportation.

The product launch date should not be treated as the factory completion date.

10. Define Quality Before Production

“High quality” means different things to different brands.

Quality requirements should be translated into measurable standards.

Before production, consider:

Measurement tolerances

Stitching requirements

Seam construction

Fabric appearance

Color consistency

Print and embroidery quality

Label placement

Acceptable and unacceptable defects

Washing or performance tests

Packing requirements

Inspection standard

At AOGU, quality is controlled through pre-production review, in-line inspection, mid-production checking, final inspection and quality-supervisor oversight.

AQL inspection standards are used to evaluate finished orders. Every order is also inspected by SGS, with an independent inspection report issued before shipment. All outbound garments pass through needle detection equipment.

Quality should be agreed before production—not debated after delivery.

11. Questions to Ask a Clothing Manufacturer

Preparation should work in both directions.

The brand provides clear product information, while the factory demonstrates whether it is capable of delivering the project.

Ask potential manufacturers:

Which product categories do you specialize in?

Do you provide OEM, ODM or both?

Can you support fabric sourcing and development?

What is your MOQ?

How is the sample process managed?

What are the expected sample and production times?

How do you control quality during production?

Do you use AQL inspection standards?

Do you accept independent third-party inspection?

Which certifications does the factory hold?

How is communication managed?

Can production capacity support future growth?

Do not evaluate a factory by quotation alone.

A lower initial price may create greater costs if sampling is inaccurate, communication is unclear, quality is inconsistent or delivery is unreliable.

A Practical Checklist Before Your First Factory Conversation

Before contacting a custom clothing manufacturer, prepare as much of the following as possible:

Brand and product brief

Target customer and market

Product category

Sketches or reference images

Tech pack, if available

Fabric expectations

Colors and size range

Estimated quantities

Target budget or retail positioning

Branding requirements

Reference garments

Quality expectations

Launch and delivery timeline

Areas where factory support is required

You do not need every answer.

The important point is to separate confirmed decisions from open questions. This gives the manufacturer a clear starting point and helps both sides use the first conversation productively.
