Private label period underwear combines a reusable garment with an integrated absorbent gusset. It can be positioned for menstrual flow, backup protection or other clearly defined use cases, but the specification must be built around the target market, wearer, absorbency claim, fit, wash durability and chemical requirements. There is no universal layer count, capacity, MOQ or unit price that applies to every design.
How Period Underwear Is Constructed
Most products use a layered gusset, although the number and order of layers vary by design. A typical system may include:
- Skin-contact layer: moves moisture away from the body and affects softness, drying and staining.
- Acquisition or distribution layer: spreads liquid across the absorbent zone.
- Absorbent layer: holds the specified volume and may use textile blends or other absorbent structures.
- Barrier layer: helps limit transfer to the outer garment.
- Outer fabric: provides fit, stretch, appearance and durability.
Layer names are not performance proof. The finished garment should be tested for capacity, rewet, leakage, drying, dimensional stability and wash durability using the approved fabric, seam and gusset construction.
Styles and Use Cases
| Style | Common positioning | Specification questions |
|---|---|---|
| Brief or bikini | Everyday menstrual use | Coverage, rise, waistband and gusset length |
| Hipster or boyshort | More side/rear coverage | Leg opening, seam placement and movement |
| High-waist | Extended body coverage | Waist support, stretch recovery and size grading |
| Teen/youth | First-period or school market | Age-appropriate sizing, instructions and packaging |
| Overnight | Longer rear coverage | Absorbent-zone geometry, leakage testing and fit while sleeping |
| Backup protection | Used with another menstrual product | Clearly limited claim and lower-bulk construction |
Fabric Selection
Fabric choice affects comfort, stretch, drying, pilling, shrinkage, colorfastness and cost. Common options include cotton blends, modal or lyocell blends, polyester/microfiber structures, nylon blends and elastane. Terms such as organic, bamboo, antibacterial, odor-control or hypoallergenic require evidence that matches the exact material and finished product.
- Define fiber percentages and fabric weight.
- Specify stretch and recovery in both directions.
- Set pilling, shrinkage and colorfastness requirements.
- Confirm skin-contact finishes, dyes and restricted-substance testing.
- Review drying time and hand feel after repeated washing.
Absorbency and Leakage Claims
Marketing labels such as Light, Moderate or Heavy are not automatically comparable between brands. A claim should identify the test method, sample size, conditioning, liquid, test direction and pass criteria. “Equivalent to X tampons” can mislead if the comparison does not use a defined tampon absorbency and validated method.
A practical test plan can include total capacity, acquisition time, rewet, leakage under pressure, edge leakage, wash-cycle performance and visual inspection of seams or delamination. Final claims should be based on the production garment—not only a laboratory fabric swatch.
Customization Options
- style, rise and leg opening;
- size range and graded measurements;
- outer fabric, color and print;
- gusset coverage and absorbency target;
- waistband, woven label, heat-transfer label or print;
- care label and consumer instructions;
- individual packaging, multipacks and retail cartons.
Every additional size, color, fabric and package format can create a separate SKU and affect material purchasing, cutting efficiency, artwork, testing, MOQ and inventory. New brands usually benefit from a focused first assortment.
MOQ, Pricing and Lead Time
These commercial terms should be quoted after the garment specification is defined. Stock fabrics and an existing pattern may have different requirements from a custom textile, custom color, new size range or unique gusset structure.
| Cost or MOQ driver | Why it matters |
|---|---|
| Fabric and trim availability | Custom knitting, dyeing and elastic can carry separate minimums |
| Size and color count | Each combination affects cutting and inventory |
| Gusset construction | Layer count, coverage, seam method and barrier material affect labor and testing |
| Packaging | Printed bags, boxes, inserts and barcodes have their own setup and minimums |
| Testing | Absorbency, durability, chemical and market-specific tests add time and cost |
| Inspection and shipping | Inspection level, Incoterm and destination change the landed cost |
Request a written quotation that states the specification, size/color split, packaging, test scope, sample stage, Incoterm and validity period. Do not rely on a generic online price range.
Sample and Approval Process
- Define use case, target wearer, style, sizes and absorbency claim.
- Select available fabric and gusset materials.
- Approve a development sample for fit and construction.
- Run wear, wash and performance evaluation on the agreed sample.
- Finalize graded measurements, colors, labels and packaging.
- Approve a pre-production sample and written specification.
- Confirm quality plan, production schedule, inspection and shipment.
Quality and Documentation Checklist
- fiber composition and material traceability;
- restricted-substance and target-market chemical requirements;
- size measurement tolerances and workmanship standard;
- absorbency and leakage test method;
- wash-cycle, shrinkage, pilling and colorfastness results;
- care instructions and claim substantiation;
- batch inspection and change-control procedure.
Frequently Asked Questions
How much liquid can period underwear hold?
Capacity varies with the gusset materials, coverage and test method. Use a product-specific tested value rather than a universal category number.
How long does period underwear last?
Durability depends on materials, construction, washing, drying and care. A brand should support any wash-cycle or lifespan claim with testing on the finished garment.
Can I use a fixed market MOQ or online price?
No single figure applies to every design. MOQ and price must be confirmed against the exact fabric, sizes, colors, gusset, labels, packaging and order split.
