Starting a clothing brand is easy. Building one people actually want to buy from is harder.

The modern version of the playbook is not “make a logo, print it on a T-shirt and launch.” Current founder-led clothing-brand content repeatedly emphasises brand meaning, community, product quality, manufacturing competence and transparency. MERCHMODE should teach the commercial and production side with the same level of realism.

01 / DEFINE THE CUSTOMER

A clothing brand does not begin with a logo. It begins with a customer.

Define: • age and lifestyle • style references • what they already buy • typical spend • communities they belong to • why they buy clothing

Avoid “everyone”. A narrower starting customer makes product, pricing, imagery and marketing decisions easier.

02 / DEFINE THE IDEA

Ask what makes the brand identifiable without the logo. That may be a silhouette, graphic language, product category, cultural point of view, material, community or recurring design system.

03 / VALIDATE BEFORE MANUFACTURING

Do not spend the maximum budget simply because you like the idea.

Look for behaviour: • email sign-ups • sample interest • event attendance • legitimate pre-orders • repeat social engagement • product requests

Interest is useful. Action is better evidence.

04 / RESEARCH THE MARKET

Study comparable brands for: • product range • retail prices • fits • garment weights • photography • customer complaints • best sellers • sold-out products • launch frequency

Research to understand the customer's alternatives, not to copy them.

05 / CHECK THE NAME

Before printing labels, investigate: • Google • social handles • relevant domains • Companies House • UK trade marks

A company registration and a trade mark are different legal concepts.

06 / DESIGN A HERO PRODUCT

Your first drop does not need ten products. One memorable hero product can simplify marketing, photography, inventory and messaging.

A practical first range might be one T-shirt, one hoodie and a small number of graphics or colourways.

07 / CHOOSE THE PRODUCTION ROUTE

ROUTE A — BLANK + DECORATION Use an existing garment and customise it through screen print, DTG, DTF, embroidery, labels and packaging.

ROUTE B — CUSTOM MANUFACTURE Develop the garment itself: fabric, GSM, fit, measurements, construction, labels, trims, colour and finishing.

For many first-time founders, strong blanks are the lower-risk starting point.

08 / UNDERSTAND GSM

GSM means grams per square metre and is one measure of fabric weight. Higher GSM generally means heavier fabric when comparing similar constructions, but GSM alone does not equal quality.

Fit, fibre, knitting, finishing, shrinkage and construction still matter.

09 / BUILD THE PRODUCT SPECIFICATION

For blank decoration specify: • exact garment • colour • quantities and size split • artwork • dimensions • placement • decoration method • labels

For custom manufacture the specification becomes much more detailed.

10 / TECH PACKS

A tech pack is the manufacturing instruction set for a custom garment. It can include: • technical flats • measurements • fabric and GSM • colour references • trims • stitching • labels • print / embroidery positions • construction notes

The more custom the garment, the more important accurate technical communication becomes.

11 / ORDER SAMPLES

Do not approve a bulk run from website photos.

Test: • fit • sizing • fabric • colour • print • embroidery • shrinkage • washing • labels • packaging

12 / SAMPLE IN STAGES

Custom products may require: • development sample • fit sample • decorated sample • production-ready sample

Approve what you can actually inspect.

13 / CHOOSE THE RIGHT DECORATION METHOD

SCREEN PRINT — strong for repeat graphic production and specialist inks. DTG — useful for detailed full-colour artwork and flexible digital production. DTF — flexible transfer method across many garment and artwork situations. EMBROIDERY — stitched finish for logos, caps, hoodies, jackets and detailing.

The best method depends on artwork, garment, quantity, finish and deadline.

14 / FIND THE RIGHT MANUFACTURER

Assess capability, not just price.

Ask: • what do you specialise in? • what are the minimums? • can you sample? • what files/specification do you need? • how is QC handled? • what drives lead time? • what happens if units fail QC?

For overseas production also model freight, duties, import VAT and delivery timing.

15 / COST THE FINISHED PRODUCT

Build a cost sheet: GARMENT / MANUFACTURE + DECORATION + LABELS + PACKAGING + FREIGHT + OTHER DIRECT COSTS = LANDED PRODUCT COST

Do not price from the blank garment alone.

16 / MODEL UNIT ECONOMICS BEFORE PRODUCTION

Calculate: • landed unit cost • intended retail price • gross profit per unit • gross margin • break-even units

Then consider payment fees, returns, marketing, tax, damaged stock and fulfilment.

17 / CHOOSE AN INVENTORY MODEL

STOCKED DROP — inventory ready before launch. PRE-ORDER — customer demand captured before final production. SMALL DROP + RESTOCK — controlled opening quantity with reorder capability.

Each model trades cash risk against customer waiting time and operational certainty.

18 / PLAN SIZE BREAKDOWN

Total quantity is not enough. Plan XS/S/M/L/XL/XXL etc. A bad size curve can leave you with stock while the sizes customers want are gone.

Record actual size sales from the first drop and use them to improve the next.

19 / BUILD THE BRAND WORLD

Identity goes beyond the logo: • photography • typography • language • casting • music • locations • packaging • recurring graphics • product names • collaborators

The goal is recognisability before the username is read.

20 / BUILD COMMUNITY BEFORE LAUNCH

Current clothing-brand creators repeatedly stress that product alone is not enough. Show the process: • ideas • sampling • mistakes • fittings • production • campaign preparation

Do not privately build for six months and introduce the audience on launch day.

21 / BUILD AN OWNED AUDIENCE

Start collecting email addresses early through: • early access • launch notification • limited drop access • event invitations

Social reach is useful; email gives you a direct channel you control.

22 / BUILD THE LAUNCH BACKWARDS

4–6 WEEKS OUT finalise samples, photograph, build email capture, prepare store.

2–3 WEEKS OUT reveal product, fit and details; seed selectively; announce date.

1 WEEK OUT publish price, sizing, delivery information and launch time.

LAUNCH DAY remove friction. Customers should know what it costs, how it fits, when it ships and where to buy.

23 / CHOOSE HOW TO SELL

Common channels: • own ecommerce • social-to-store • pop-ups • events • wholesale • pre-orders

Many brands use several together.

24 / PLAN FULFILMENT

After purchase, someone must store, pick, pack, label, ship and handle returns. A manual system can work for 30 orders and collapse at 3,000. Build for the next realistic stage, not imaginary scale.

25 / YOUR FIRST DROP IS RESEARCH

After launch review: • traffic • conversion • best products • size mix • acquisition channel • content performance • returns • customer feedback

The next drop should be smarter because the first one existed.

26 / SIMPLE 20-STEP ROADMAP

01 Define the customer 02 Define the idea 03 Validate demand 04 Research the market 05 Check the name 06 Choose the hero product 07 Choose blanks or custom manufacture 08 Build the production specification 09 Order and revise samples 10 Choose decoration 11 Build full unit economics 12 Decide inventory strategy 13 Build the brand world 14 Create campaign content 15 Build email/community 16 Plan quantity and size split 17 Plan launch backwards 18 Produce and quality check 19 Launch and fulfil 20 Analyse, learn and reorder smarter

27 / MERCHMODE'S ROLE

You do not need to become a manufacturing expert before sending the brief.

Tell us: • what you want to make • roughly how many • deadline • reference images • target feel and quality

MERCHMODE can help structure the production route.
