The fashion design process for your clothing, like designer shirts, pants, blazers, etc., is an important one for any successful garment business. From the original spark of an idea to mass production on the production line, it is vital. Although, every designer and brand can mould the process depending on their workflow, the fundamental stages stay the same throughout.
Whether you are beginning a new apparel collection or are looking to fine-tune your brand, knowing every step of the process makes it so that your designs are cohesive, technically sound and market-ready. Read on for the full 8-step process: a guide that brings expert advice, real-life concepts, and how Armour helps brands realise their vision his way together in one place.
What is the Fashion Design Process?
The apparel design process is not all creativity; it’s structured problem-solving. It’s all part of a greater ecosystem: inspiration, illustration, technical development, sourcing, sampling, fitting, approvals and production.
Step-by-Step Guide on Fashion Design Process
Step 1:- Idea/ Vibe Board/ Inspiration
Responsibility: Designer
In the industry life cycle, the very beginning part is ideation in the clothing design process. This is when your creativity turns into a planned course. Designers gather inspiration from:
- Pinterest boards
- Magazines, books, and photography
- Nature, textures, architecture, interiors
- Colour stories and trend forecast sites
How the Mood Board “Comes Through”?
Step 1: Collect Inspiration
Collect everything you find inspiring about the look — shapes, textures, colours, moods and themes.
Step 2: Compile Ideas
Begin sketching or jotting down any silhouettes, construction ideas, trims and fabrications in a design process fashion. Templates are very useful here to get a quick visual.
Step 3: Create the Mood Board
Try to find some common ground among your inspirations. Create a board with images, fabric swatches, colour palettes and textures. This mood board serves as the visual “north star” for all development.
Step 2:- Sketches / Fashion Illustration
Responsibility: Designer
When the mood board for a new dress design is approved, designers take to sketching. At this stage, it's all about the adventure:
- Try multiple silhouettes
- Experiment with style variations
- Draw croquis to show proportion accurately
Once the best direction has been chosen, the designer creates a finished fashion sketch, which might be broken down into:
- Fabric swatches
- Color application
- Presentation of movement and drape
This drawing in the garment design process then becomes an aesthetic reference road map to work from for the technical team.
Step 3:- Technical Sketches (CAD / Flats)
Responsibility: Technical Designer
Flats, technical sketches or CADs are the blueprints of the garment. They have to be precise and as specific as possible because they are the instructions that pattern makers and factories follow.
A proper technical flat in the fashion design process includes:
- Front and back view
- Correct proportions
- Sewing, Seams and Construction Details
- Pocket placements, trim placements
- Closure type and location
These drawings avoid guesswork and costly shop errors.
Step 4:- Tech Pack
Responsibility: Technical Designer + Sourcing Team.
The tech pack is the ultimate instruction manual for manufacturing after the dress design drawing. It includes:
- Measurement specs
- Construction details
- Fabric and trim selections
- Stitch types
- Label and packaging instructions
- Technical flats
- Colorways
- BOM (Bill of Materials)
The garment production management team collaborates during this step to finalise which materials will be used and from where.
Step 5:- Sourcing
Responsibility: Sourcing Agent / Developer
Sourcing is essentially the “shopping phase” for your garment. Here you identify:
- Factories for manufacturing
- Fabric suppliers
- Trim suppliers (zippers, buttons, elastics, etc.)
- Labels and packaging suppliers
You may also work with a full-service factory that handles everything end-to-end. This step determines quality, cost, and production feasibility.
Step 6:- Sampling
Responsibility: Factory.
Once tech packs and materials are ready in the fashion design process, the factory begins sampling. This phase includes multiple rounds:
- Prototype sample
- Fit sample
- Revised samples after feedback
- Approved sample.
Sometimes factories use substitute fabrics or trims in early samples to speed up development while waiting for custom trims or dyed fabrics. Early samples often come in unusual colours or fabrics collection—this is normal. Sampling continues until the garment matches all specifications in the tech pack.
Step 7:- Fit, and Review
Responsibility: Technical Designer + Development Team.
Fit sessions are crucial after building sketch drawings for new garments. Each sample is evaluated for:
- Proportion
- Comfort
- Movement
- Construction accuracy
- Fabric behavior
After each review, corrections are added to the tech pack and the next sample is requested. This cycle repeats until the prototype is perfect. Consistent fit across sizes is also established during this stage, especially if the design will be graded for a full size range.
Step 8:- Design Approval
Responsibility: Development Team.
Once the final prototype meets all expectations:
- The tech pack is updated one last time
- The design is approved
- A pre-production (PP) or top-of-production (TOP) sample is requested
- Design approval locks in materials, measurements, colours, and finishing details
Step 9:- Production
Responsibility: Factory.
Now the garment enters mass production:
- Grading (creating size variations)
- Cutting
- Stitching
- Quality control (QC)
- Finishing
- Packaging.
Once production is completed, garments are shipped to the brand or retailer. This is where your entire fashion design process comes to life at scale.
