Your Sourcing Roadmap

Sourcing children’s underwear and sleepwear is a chain of decisions, and the order matters. A fabric chosen before you understand flammability rules can force a redesign. A factory quoted before you have a tech pack will quote a number that changes later. These six stages follow the sequence buyers actually work through.

Stage 01

Find & Vet Suppliers

Who should I manufacture with?

Channels that produce working relationships vs the ones that mostly produce noise — and how to shortlist 3 serious candidates.

Stage 02

Define the Product

What exactly should I ask the factory to make?

Tech packs, fabric, waistbands and construction — the specifications that turn an idea into a quotable product.

Explore the Sourcing Library

Forty-plus buyer-facing guides, organised by the stage of sourcing they answer. Start where you are.

Why This Sourcing Library Exists

Most buyers start on a marketplace and get overwhelmed by listings that all look identical. The advice that actually helps comes from the questions you haven’t asked yet — whether a vendor is genuinely a factory or a trading company, what the realistic MOQ is for your colourway, and what testing documentation you will need to clear customs in your market.

What This Guide Helps You Decide

Working through the six stages should leave you with a clear answer to each of these:

Which suppliers to shortlist
What specifications to prepare
What MOQ to expect per colourway
What testing to request
How to control production
How to calculate your landed cost

Built on What We See on the Production Line

The fabric, compliance and development guidance on this page applies whoever you manufacture with — it is not a sales pitch disguised as neutral knowledge. The commercial observations, on MOQ, sampling fees and lead time, reflect what we see on our own production lines and are worth testing against a second supplier before you rely on them.
