Launching a loungewear brand? Follow our step-by-step guide on sourcing knitwear, avoiding common China manufacturing pitfalls, and scaling your production.

How to Start Your Private Label Loungewear Line: A Step-by-Step Sourcing Guide

Let’s be honest: launching a clothing line is a logistical puzzle. You have the vision and the audience, but moving from a mood board to a physical product that people actually want to buy is where most brands get stuck.

In 2026, the "Private Label" model is more competitive than ever. To succeed, you don't just need a factory; you need a supply chain partner who understands the nuances of knitwear.

Whether you are a startup or an established brand pivoting into loungewear, this guide breaks down the sourcing process and the pitfalls you must avoid.

Step 1: The Tech Pack (Your Blueprint)

Many startups make the mistake of sending a factory a photo of a competitor's hoodie and asking, "Can you make this?"

A professional Tech Packis essential. It should include:

Detailed Sketches:Front, back, and side views.

BOM (Bill of Materials):Fabric type, GSM, thread color, and trim details (zippers, drawstrings).

Size Grading:Measurements for XS through XXL.

SML Tip:If you don't have a tech pack yet, don't panic. We often work with brands to develop these based on their initial concepts or "reference samples."

Step 2: Fabric Sourcing & Lab Dips

In loungewear, the fabric isthe product. This is where you decide between a breathable 160 GSM jersey for summer sleepwear or a cozy 350 GSM French Terry for winter joggers.

Once the fabric is chosen, we move to Lab Dips—small swatches of fabric dyed to match your specific Pantone colors.

Pitfall to Avoid:Never approve a color based on a computer screen. Always check physical swatches under natural light.

Step 3: The Sampling Phase (The "Make or Break")

Sampling is where your vision comes to life. You will receive a Proto Sampleto check fit and construction.

Common Pitfall:Rushing this stage. It’s tempting to skip a second round of samples to save time, but a small fit issue in sampling becomes a massive headache in bulk production.

Step 4: Bulk Production & Quality Control

Once the "Gold Sample" is approved, bulk production begins. This is where most "China sourcing horror stories" happen. To ensure quality, we implement:

In-line Inspection:Checking garments while they are still on the sewing line.

Final AQL Inspection:A statistical check of the finished goods before they are packed.

Pitfall to Avoid:Lack of transparency. Many "manufacturers" are actually middle-men who outsource your order to smaller, unverified workshops. At SML Intimate, we maintain full control over our production lines to ensure consistency.

Step 5: Logistics and Lead Times

In 2026, global logistics require careful planning. A typical production cycle might take 30-45 days, plus shipping time.

Pro Tip:Always factor in a 10-day "buffer" for unforeseen holidays or port delays.

5 Common Pitfalls to Avoid When Sourcing from China

Chasing the Lowest Price:If a quote is 30% lower than everyone else, they are likely cutting corners on fabric quality or ethical labor practices.

Vague Communication:"Soft fabric" means different things to different people. Use technical terms like "brushed finish" or "silicon wash."

Ignoring MOQ (Minimum Order Quantity):Startups often struggle with high MOQs. Look for a partner (like us) who offers flexible MOQs for growing brands.

Skipping the "Squat Test":For leggings and joggers, ensure the knit density is high enough to be squat-proof.

Underestimating Packaging:Your "unboxing experience" is part of your brand. Don't forget to source custom polybags and hangtags early.
