Starting a Private Label Clothing Line
Before You Start
The apparel industry has the highest return rate of any ecommerce category, averaging 20 to 30 percent for online clothing sales compared to 3 to 5 percent for most other product categories. Every return costs you shipping, restocking, and often the inability to resell the item at full price. This reality means your actual net margins on clothing are 10 to 20 percent after returns, not the 50 to 65 percent gross margin that looks attractive on paper. Successful apparel brands manage returns through accurate size guides, detailed product photography on diverse body types, and fabric descriptions that set correct expectations.
The other unique challenge with clothing is SKU proliferation. A single style in 5 sizes and 3 colors creates 15 SKUs. Three styles become 45 SKUs. Each SKU needs inventory, and predicting demand across sizes and colors is notoriously difficult. For your first private label clothing launch, limit yourself to 1 to 2 styles in your most popular color with a focused size range to keep inventory investment manageable and gather real sales data before expanding.
Budget $5,000 to $20,000 for a clothing line launch. This covers tech pack development ($200 to $800), fabric and sample costs ($300 to $1,000), first production run across sizes ($2,000 to $10,000), custom labels, hang tags, and packaging ($300 to $1,000), model photography ($500 to $2,000), and marketing and launch budget ($1,000 to $5,000).
Choosing Your Apparel Niche
The apparel market is enormous, exceeding $350 billion annually in the US, but generic clothing brands fail because they compete against fast fashion giants with infinite budgets and established supply chains. Successful private label clothing brands target specific niches where they can differentiate: activewear for a specific sport or activity, loungewear and basics with premium fabrics, workwear for specific professions (nursing scrubs, construction, hospitality), plus-size activewear or fashion, sustainable and eco-friendly clothing using organic or recycled materials, or niche accessories (beanies, socks, scarves, belts). The tighter your niche, the easier it is to build a loyal audience that finds your brand through specific search terms and recommends it within their community.
Finding a Garment Manufacturer
Garment manufacturers specialize by product type, fabric type, and production volume. Search for manufacturers through Alibaba (the largest selection, primarily Chinese, Bangladeshi, and Vietnamese factories), Maker's Row (US-based manufacturers, strong for premium and small-run production), Sewport (connects brands with vetted garment manufacturers worldwide), and Kompass (international manufacturing directory). Contact 8 to 12 manufacturers with your product concept, including the type of garment, intended fabric, estimated order quantity per style per size, and any special construction requirements (moisture-wicking, four-way stretch, reinforced seams). Request fabric swatches, their standard size chart, pricing by order quantity, MOQs per style and per color, and lead times. Narrow to 3 to 4 candidates for sampling.
MOQs for garment manufacturing are typically higher than other private label categories. Chinese manufacturers commonly require 100 to 500 units per style per color, meaning a single style in 3 colors costs 300 to 1,500 units minimum. US manufacturers on Maker's Row sometimes accept 50 to 100 units per style but at significantly higher per-unit costs ($15 to $40 per garment versus $3 to $12 from Asian manufacturers). For a first-time clothing brand with limited capital, some manufacturers will negotiate lower MOQs in exchange for a slightly higher per-unit price, especially if you demonstrate a credible marketing plan and growth potential.
Developing Your Products
A tech pack is the blueprint for your garment. It specifies every detail the manufacturer needs to produce the product: fabric composition and weight (for example, "95% organic cotton, 5% elastane, 180 GSM jersey"), color specifications using Pantone codes, detailed measurements for each size, construction details (seam types, stitch counts, hem widths), label placement and label content, hang tag and packaging specifications, and any special features (pockets, zippers, embroidery, screen printing). If you do not have experience creating tech packs, hire a freelance fashion designer on Upwork or Fiverr ($100 to $500 per tech pack) to translate your concept into a production-ready document. Send the tech pack to your manufacturer and request pre-production samples for review.
When samples arrive, evaluate them against your tech pack specifications. Check that the fabric weight, drape, and hand feel match your expectations. Measure every dimension against the size chart and verify accuracy within 0.5 inches. Test the garment through multiple washes to check for shrinkage (acceptable shrinkage is under 3 percent), color fading, pilling, and construction durability. Have 3 to 5 people in different body types try on the sample to verify the fit works across your target demographic. Provide detailed feedback to the manufacturer and request revised samples for any issues before approving production. Rushing through sampling to save time is the most common reason new clothing brands end up with inventory that does not sell.
Sizing and Size Distribution
For your first production run, offer a core size range rather than trying to cover every size. A common starting range is S through XL (4 sizes) or XS through XL (5 sizes). Order more units in the middle sizes (M and L), which typically account for 55 to 65 percent of sales, and fewer in the extremes (XS and XL). A standard size distribution for a 500-unit order across 5 sizes might be: XS 10%, S 20%, M 30%, L 25%, XL 15%. After your first sales cycle, adjust the distribution based on actual demand data. Offering inclusive sizing (XS through 3XL or beyond) is a strong differentiator but requires significantly higher inventory investment and more complex fit testing. Consider expanding your size range in your second production run once you have sales data to guide ordering.
Labeling Requirements for Apparel
The Federal Trade Commission requires specific information on clothing labels sold in the United States. Every garment must have a fiber content label listing all fibers by percentage in descending order (for example, "60% Cotton, 35% Polyester, 5% Elastane"), a country of origin label ("Made in China," "Made in USA," etc.), care instructions using either standardized symbols (ASTM D5489) or written instructions, and the manufacturer's name or registered identification number (RN). These labels are typically sewn into the garment during manufacturing. Provide your manufacturer with the exact text and placement specifications for each label type. Woven labels with your brand name and care information cost $0.10 to $0.30 per garment at production quantities.
For your brand label (the one customers see), options include woven labels sewn into the neckline or waistband, heat-transfer labels printed directly onto the fabric, and hang tags attached to the garment with your brand story and care information. Premium brands tend to use woven labels and high-quality hang tags, while budget brands use heat-transfer labels to reduce per-unit cost. See the full labeling requirements guide for details on compliance across different product categories.
Selling Clothing Online
Clothing sales depend more heavily on photography and presentation than any other ecommerce category. Invest in professional model photography showing each garment from multiple angles, in natural poses, and ideally on models representing your target demographic. Include flat-lay product photos for detail shots, close-ups of fabric texture, stitching, and special features, and a size guide with specific measurements in inches and centimeters. List products on your own Shopify store where you control the brand experience and earn higher margins, and consider Amazon as a secondary channel for volume (though clothing return rates on Amazon are particularly high). Build an Instagram and TikTok presence with styling content, behind-the-scenes manufacturing stories, and customer photos to drive brand awareness and direct traffic to your store.
The biggest lever for reducing returns in online clothing sales is setting accurate expectations. Provide a detailed size guide with measurements for each size (chest, waist, hip, length, sleeve length), a fit description (slim fit, regular fit, relaxed fit, oversized), fabric weight and stretch characteristics, and model measurements ("Model is 5'8", wearing size M"). Brands that invest in detailed size information and fit descriptions consistently see return rates 5 to 10 percentage points lower than brands that provide minimal sizing information. Given that each prevented return saves $5 to $15 in shipping and processing costs, this is one of the highest-ROI investments a clothing brand can make.
Managing Inventory and Cash Flow
Clothing inventory management is more complex than most private label categories because of the size and color matrix, seasonal demand shifts, and the speed at which fashion trends change. For your first production run, order conservatively and plan to reorder quickly once you have sales data. Running out of a popular size temporarily is far less damaging than being stuck with hundreds of units that do not sell.
Cash flow is the biggest operational challenge for new clothing brands because production orders require significant upfront capital, and the time between paying the manufacturer and receiving revenue from sales can be 8 to 16 weeks. If your first order costs $8,000 and takes 6 weeks to produce, 3 weeks to ship, and 4 weeks to sell through, you need enough working capital to cover 13 weeks of expenses before the revenue cycle starts.
