What’s The Difference Between A Sketch & A Tech Pack?

If you’ve got a Pinterest board full of outfit inspiration, a head full of ideas, and a dream of launching your own clothing brand then you’re in the right place.

Maybe you’ve saved photos of details you love... silhouettes that speak to you... colours that feel so you. You know the vibe of your brand, you can see it in your head, but then you hit a wall wondering how to get from A to B. And worse still, now you’re wondering:

“Do I have to learn how to sketch like a designer?”“Do I need fancy design software?”“Should I send these inspiration photos to a manufacturer and hope they get what I mean?”

Let’s stop right there because this is where so many fashion startup founders go wrong.

The Sketch vs Tech Pack Confusion

You might have heard both these terms, but what do they actually mean? And more importantly, do you need to learn how to create them yourself?

Let’s clear things up.

What Is a Sketch?

A sketch is your design in visual form. It shows the style, the overall silhouette, colours, key features such as the neckline, length, and general feel of the garment. It sometimes can be a creative expression of your idea.

Sketches can be:

Hand drawn
Created digitally in apps like Illustrator
Basic outlines and impressions
Detailed fashion illustrations - we call them fashion flats

But here's the thing: A sketch on its own, even a great fashion flat, is not enough to get something manufactured properly. It’s just the starting point.

And if the idea of sketching makes you panic, don’t worry, you don’t need to be an artist to start a fashion brand. Most of the founders I work with can’t draw at all.

What Is a Tech Pack?

A tech pack (short for technical package) is the instruction manual for your design. It’s what your manufacturer needs to understand exactly how to make your garment, down to the last detail.

A great tech pack includes:

Front and back technical drawings called fashion flats (not rough sketches!)
Construction notes
Fabric and trim specifications
Measurements and size charts
Pantones, colourways and variations
Branding and labelling placement
Technical information on any prints, embroideries or embellishments
Any other technical info specific to the item for example the type of machinery needed

While a sketch shows the idea, the tech pack shows the how.

Why You Can’t Just Send Photos to a Factory

This is one of the biggest mistakes I see new founders make. They pull together a few reference images and email them to a manufacturer, assuming they’ll "figure it out."

But here’s the reality:

Manufacturers don’t read minds
They don’t guess what fabric you want or what size you’re aiming for
They definitely won’t get it right from a mood board alone

Sending just photos or screenshots often leads to poor samples, delays, and serious miscommunication. And it’s a costly mistake to fix and I've seen it so many times where people come to me to start again.

Do I Need to Learn Fancy Design Skills Then?

Not at all.

You do not need to learn how to create technical designs yourself, master Adobe Illustrator or take a fashion design degree. That’s my job.

Inside my course, The Fashion Startup Academy, I teach you:

What a tech pack is
How it fits into the product development process
Why it’s essential for getting great samples made

But you won’t be expected to make one yourself.

That’s where I come in. I offer a professional tech pack creation service for startup founders just like you. You bring the idea, I translate it into factory-ready documentation.

What If I’m Still in the Pinterest Phase?

That’s fine, everyone starts there.

But if you’re serious about turning your inspiration into a real brand, it’s time to move from mood boards to manufacturing-ready.

Start by getting clear on your vision:

What do you want to create?
What are the key features?
Who is it for?

Then book a consultation or tech pack package with me. I’ll help you take those scattered ideas and turn them into professional, production-ready plans.

Let’s Do This Right

Starting a fashion brand is exciting, but it’s also a process. Skipping the technical steps might feel faster now, but it’ll slow you down later.

Instead of wasting time, money, and energy on poor samples and confusing back and forth with factories, get it done properly from the start.

A sketch (even a rough one) brings your idea to life

A tech pack turns that idea into something you can actually make

And with expert support, you don’t have to do it all yourself
