1. Wanting to start too big and too complex

The biggest mistake: starting with a half collection as if you are already a big brand. Ten models, many different fabrics, multiple colors, and complicated details. That sounds ambitious, but is often a recipe for delays, mistakes, and high costs.

What is going wrong here:

• your budget is getting spread too thin over too many products
• you lose focus in design and communication
• your inventory risk becomes unnecessarily large
• your sample and development costs are skyrocketing

Better: start with a compact capsule. Think of 3 to 7 models that work well together, with a limited number of colors. Then expand as you see what works.

2. No clear target audience or concept

"My brand is for everyone" sounds nice, but in practice, it's a dead end. Without a sharp target audience and clear concept, you can't make consistent choices in style, price, material, and marketing.

Signals that your target audience is too vague:

• you can't say in one sentence for whom you are making clothing
• you keep changing style and direction
• you find it difficult to determine prices
• you don't know where your customer shops and what they are currently missing

Resolve this first before planning your production. For example, use our blog defining concept and target audience for your clothing line as a starting point.

3. Going to production too quickly

Another classic mistake: wanting to go directly into production after one sample. Or even without a sample, "because it will surely be fine". This almost always leads to disappointments, extra costs, or products that you are not happy with.

Common phrases that are warning signs:

• "We'll adjust it later in the next production"
• "The customer won't notice those small mistakes anyway"
• "We don't have time for a second sample"

The sample phase is precisely there to eliminate mistakes before you produce dozens or hundreds of pieces. Take that phase seriously, no matter how impatient you are to go live.

4. Not calculating, but dreaming

Creative energy is worth gold, but without calculations, your brand remains an expensive hobby. Many starters do not have a clear picture of:

• total cost price per item (including all hidden costs)
• required selling price to make a margin
• how many pieces they really need to sell to break even

Consequence: either the selling price is too low, or the margin is so tight that every discount hurts.

At a minimum, work with a simple spreadsheet that includes all costs: development, production, labels, packaging, shipping, marketing, and platform costs. Use our blog what does it cost to start a clothing line as a basis.

5. Forgetting labels, legislation, and UPV

Another pitfall: only thinking about care labels, material listings, claims, and future obligations like UPV textiles at the last minute. While this directly relates to:

• the information your customer needs
• your liability if something goes wrong
• how your brand is perceived in terms of fairness and sustainability

It's better to arrange this in the sample phase rather than when production is already finished. Also read: care labels and legal requirements for clothing brands and UPV legislation for textiles.

6. Choosing the wrong production partner

The cheapest option is rarely the best. Many brands choose a production address purely based on price, without considering communication, reliability, and minimum quantities.

The risks of this:

• long delivery times and poor accessibility
• quality that does not match the samples
• MOQ turns out to be larger than expected
• difficult to claim if something goes wrong

Better: choose a partner who thinks along with you, is honest about what can and cannot be done, and has experience with startups. For example, see how we work on clothing production and starting a clothing line in the Netherlands.

7. Not testing, but scaling up

Another recurring pattern: immediately ordering large quantities without ever testing whether the target audience really wants the product. No pre-orders, no small batches, no feedback rounds with real users.

Smarter:

• start with a small series and gather feedback
• use a pre-order or mini-drop to gauge demand
• only adjust your designs based on what you've learned when scaling up

8. Wanting to do everything alone

Many founders try to do everything themselves: design, production, administration, marketing, photography, and social media. This is understandable, but rarely sustainable.

You don't have to build a whole team right away, but:

• find a studio that thinks along about feasibility
• hire a photographer for the first collection
• consult with someone who understands pricing and margins

This way, your brand remains a business, not just a hobby that has gotten out of hand.
