An OEM casual clothing manufacturer produces garments based on a brand’s own designs, specifications, and branding requirements.
The typical OEM process includes:
- design development
- tech pack preparation

Manufacturers such as Bless Clothing support brands throughout this process by providing custom casualwear production services.
What OEM Means in Clothing Manufacturing
OEM stands for Original Equipment Manufacturer.
In apparel production, OEM manufacturing means the factory produces garments based on the brand’s designs and requirements.
The brand usually provides:
- design concepts
- tech packs
- logo artwork
- size specifications
The manufacturer is responsible for producing the garments according to these instructions.
This model allows clothing brands to maintain full control over product design and branding.
OEM vs ODM in Apparel Production
Understanding the difference between OEM and ODM manufacturing is important for clothing brands.
| Manufacturing Type | Description |
|---|---|
| OEM | factory produces garments based on brand designs |
| ODM | factory provides pre-designed products for branding |
| private label | brand adds its logo to existing products |
OEM manufacturing offers greater design flexibility but usually requires more product development work.
Step-by-Step OEM Manufacturing Process
The OEM apparel production process involves several stages.
1. Product Concept and Design
The brand defines the product idea, including:
- garment type
- target market
- design style
Many casualwear brands begin with core items like T-shirts or hoodies.
2. Tech Pack Preparation
A tech pack contains detailed production information such as:
- measurements
- fabric specifications
- stitching instructions
- label placement
Clear tech packs reduce production errors.
3. Fabric and Material Sourcing
Manufacturers help brands source suitable fabrics and trims.
Typical casualwear fabrics include:
| Fabric | Common Use |
|---|---|
| cotton jersey | T-shirts |
| fleece | hoodies |
| French terry | sweatshirts |
| cotton blends | everyday casualwear |

4. Sample Development
Before bulk production begins, manufacturers create prototype samples.
Samples allow brands to evaluate:
- fit and sizing
- fabric comfort
- construction quality
- branding placement
Most garments require multiple sample revisions.
5. Bulk Production
Once samples are approved, the manufacturer begins large-scale production.
Typical production steps include:
| Production Step | Description |
|---|---|
| fabric cutting | preparing garment panels |
| sewing | assembling garments |
| printing/embroidery | adding logos |
| finishing | trimming and ironing |
Factories use assembly-line production systems to improve efficiency.
6. Quality Inspection
Quality control checks ensure garments meet brand standards.
Typical inspections include:
- measurement verification
- stitching inspection
- fabric defect checks
- printing accuracy
International quality standards are often based on systems such as ISO manufacturing guidelines.
7. Packaging and Shipping
After inspection, garments are packaged and prepared for shipment.
Common packaging elements include:
- polybags
- hang tags
- woven labels
- cartons
Products are then shipped to brand warehouses or fulfillment centers.
Typical Products Made by OEM Casualwear Manufacturers
OEM casual clothing manufacturers typically produce a wide range of garments.
| Product Type | Description |
