Inside a 990-Yen T-Shirt - Production Cost Is Roughly 200 Yen
A T-shirt selling for 990 yen at a fast fashion brand has a production cost (manufacturing cost) of roughly 150 to 250 yen.
Fabric: approximately 60 to 100 yen. For 100% cotton, a single T-shirt uses about 200 to 250 grams of fabric. Combining the international cotton price with processing costs, one shirt runs 60 to 100 yen. Polyester blends are even cheaper.
Sewing: approximately 50 to 80 yen. Labor costs at garment factories in Bangladesh and Vietnam. Sewing one T-shirt takes about 10 to 15 minutes. Local garment workers earn roughly 50 to 100 yen per hour.
Accessories (tags, buttons, packaging): approximately 10 to 20 yen.
Shipping and tariffs: approximately 30 to 50 yen. Ocean freight by container ship, customs clearance, and domestic delivery. Economies of scale from bulk shipping keep the per-unit cost low.
Add it all up and the manufacturing cost lands at roughly 150 to 250 yen. Against a retail price of 990 yen, the cost ratio is about 15 to 25% - lower than the 30 to 35% cost ratio typical of restaurants. Search "Tバック" on Amazon
Where Does the Remaining 750 Yen Go?
Between a 200-yen production cost and a 990-yen retail price sits a gap of 790 yen. Here is how it breaks down.
Brand gross margin (the spread between wholesale price and production cost): approximately 200 to 300 yen. Fast fashion brands wholesale to their retail division (their own stores) at 2 to 3 times the production cost. This spread is the brand's gross margin, covering design costs, quality control, and headquarters staff.
Store operating costs: approximately 300 to 400 yen. Tenant rent (10 to 15% of sales), store staff wages, utilities, and interior maintenance. Fast fashion brands that occupy large flagship stores in prime city-center locations spend 100 to 150 yen per garment on rent alone.
Advertising and promotion: approximately 50 to 100 yen. Social media ads, influencer marketing, and catalog production.
Waste and markdown losses: approximately 50 to 100 yen. The cost of marking down or discarding unsold inventory. Fast fashion operates on a mass-production, mass-disposal business model, with an estimated 20 to 30% of production going unsold. This disposal cost is passed on through the price of items that do sell.
Uniqlo vs. SHEIN - What Accounts for the Price Gap?
Even within "fast fashion," there is a significant price gap between a Uniqlo T-shirt (990 to 1,500 yen) and a SHEIN T-shirt (300 to 500 yen).
Quality difference. Uniqlo invests heavily in fabric quality control. Cotton grade, sewing precision, and wash durability are all higher than SHEIN. The difference in fabric and sewing costs is about 50 to 100 yen per garment.
How they handle inventory risk. Uniqlo uses "planned production," setting output based on demand forecasts. SHEIN uses "test production," manufacturing small batches and scaling up only after gauging sales. SHEIN's approach generates less waste, and those savings are reflected in the price.
Whether physical stores exist. SHEIN is online-only with no brick-and-mortar locations. Store operating costs (300 to 400 yen per garment) drop to zero. This is the single biggest factor behind the price gap.
As explained in the economics of free shipping, online-only retailers eliminate storefront costs but incur logistics costs instead. However, logistics costs are far lower than store costs, making it easier for online-only brands to offer lower prices.
How to Optimize What You Spend on Clothing
With an understanding of fast fashion's cost structure, here are practical ways to optimize your clothing budget.
Think in "cost per wear." A 990-yen T-shirt worn 10 times costs 99 yen per wear. A 3,000-yen T-shirt worn 50 times costs 60 yen per wear. Buying slightly more expensive clothes and wearing them longer can actually lower your cost per wear compared to frequently replacing cheap ones.
Time your purchases around sales. As covered in the rules of sale timing, the biggest apparel sales hit in January and July. Buying end-of-season items at 50 to 70% off gets you close to production-cost pricing.
Use resale apps. As explained in how resale app pricing works, secondhand clothing trades at 30 to 50% of the original retail price. For branded items, the quality is more than adequate.
Uniqlo for staples, SHEIN for trends. For wardrobe staples you will wear for years (white T-shirts, denim, knitwear), prioritize quality and go with Uniqlo. For trend-driven pieces you will only wear for one season, SHEIN's low prices make perfect sense. Matching the retailer to the purpose is the most rational approach.
