Why Start an Underwear Line?

The global underwear market is valued at over $110 billion and growing steadily. D2C startups are disrupting the industry by offering:

Plus-size or gender-inclusive designs

Clarify your values, aesthetic, and target customer. This foundation will guide your design and manufacturing decisions.

Step 2: Design Your Underwear Line

Consider key design factors:

Fabric: soft, breathable materials like cotton, modal, bamboo, or recycled fibers
Fit: prioritize comfort and flexibility; offer diverse sizes
Styles: briefs, boxers, bralettes, bikinis, high-waist, etc.

Work with a manufacturer that offers custom sampling to refine your product.

Look for a partner with:

Experience in intimate apparel production
Small batch manufacturing (low MOQs)
