Clothing is one of the highest-risk product categories on 1688. The upside is real — direct factory pricing, enormous style variety, and private-label flexibility that platforms like AliExpress simply can't match at scale. The downside, if you skip the due diligence, is a wave of returns, chargebacks, and one-star reviews that will follow you for months.
This guide cuts through the generic advice and gives you a concrete, step-by-step process for sourcing apparel from 1688 — with a specific focus on the three things that actually kill clothing businesses: sizing, fabric quality, and supplier vetting.
1688 is Alibaba Group's domestic Chinese wholesale marketplace. Unlike AliExpress — which is built for international retail buyers — 1688 is designed for Chinese businesses buying directly from manufacturers. That means no export markup, no middleman margin, and prices that are often 30–60% lower than the same products on AliExpress for equivalent quality tiers.
The trade-off is friction. The platform is almost entirely in Mandarin, most suppliers don't ship internationally, and payment requires a Chinese Alipay account or a proxy service. For Shopify sellers serious about their margins, though, these are solvable problems — not dealbreakers.
Many of the AliExpress and Alibaba sellers you compete with are already sourcing from 1688 behind the scenes. Going directly gives you the same upstream advantage they quietly use.
Apparel sizing is where most international sellers get burned — and it's almost entirely preventable with the right knowledge upfront.
Chinese garments are cut with a slimmer profile, narrower shoulders, and shorter sleeve lengths compared to Western-fit clothing. A Chinese "XL" in a clothing listing is often closer to a US Medium in practice. This is not a defect — it's a design standard built for the domestic market, where a trim, fitted silhouette is the norm.
Never trust the letter label alone. Always request flat-lay measurements in centimeters for every key measurement point: chest/bust, waist, hips, shoulder width, and inseam or length. Cross-reference those numbers against your own size chart — not the supplier's letter equivalents.
On 1688 listings, you'll often see size codes like 160/84A or 175/92B. This is China's national garment sizing standard (GB/T 1335). Here's how to read it:
Understanding this system lets you match sizes accurately across different suppliers and avoid the guesswork of letter-to-letter conversions.
If you've browsed 1688 for women's tops or knitwear, you've seen listings labeled 均码 (jūn mǎ), translated as "Free Size" or "One Size Fits All." This is one of the most common reasons clothing dropshippers get hit with returns. "Free Size" doesn't mean the garment stretches to fit everyone — it means the manufacturer made a single size and didn't assign it an S/M/L label. In practice, that one size is designed to fit approximately bust 80–88cm and waist 62–70cm, which is roughly a US XS to M. Customers who are US Large or above will likely find it too small.
If you sell Free Size items, never list them as "One Size Fits All" on your Shopify product page. Instead, include the exact cm measurements and note the approximate Western size range — for example: "Fits approximately bust 80–88cm / US XS–S–M." That one line of copy can dramatically reduce your return rate.
Low-cost manufacturers often don't account for fabric shrinkage in their size charts. After one wash, a borderline "Medium" can easily become a "Small" — particularly with cotton-heavy blends. When you receive samples, always wash them once before you measure. If a supplier can't tell you the pre-wash vs. post-wash measurements, that's a red flag.
Fabric quality on 1688 varies enormously — from production-line polyester that pills after three wears to genuinely well-constructed cotton blends that hold up for years. The difference is almost never visible in listing photos. You have to know what to ask.
Always order a physical sample before any bulk commitment. Request fabric swatches if possible — evaluate the hand-feel, weight, and stretch before approving production. Wash it, stretch it, and hold it to the light to check for thin spots or uneven weave.
The 1688 supplier rating system gives you several data points that experienced buyers prioritize. Here's what actually matters for apparel:
| Metric | What It Tells You | Target Benchmark |
|---|---|---|
| Repurchase rate (复购率) | % of buyers who order again — the single best quality proxy | 30%+ is strong for apparel |
| Years on platform | Supplier stability and track record | 3+ years preferred |
| Number of employees | Indicates factory scale and production capacity | 50+ for reliable bulk orders |
| Negative review handling | How disputes are resolved — read the responses, not just the scores | Active, professional replies |
| Transaction volume | Confirms the supplier is actively selling, not dormant | Consistent recent activity |
Use photo search to your advantage. Upload an image of the style you want, and 1688's visual search will surface multiple suppliers making the same or similar garment. This lets you compare quality, price, and responsiveness across factories before committing to any single source.
Also: contact at least 3–5 suppliers for the same style. Compare not just the price quote, but how quickly they respond, how much detail they provide unprompted, and whether they push back on your sizing questions with actual knowledge or just generic answers. The supplier who asks clarifying questions is almost always more reliable than the one who says "yes" to everything immediately.
Skipping samples is the single most expensive mistake apparel sellers make on 1688. The process takes 1–3 weeks and costs a fraction of what a bad bulk order will cost you in returns, refunds, and reputational damage.
If you're scaling beyond sample quantities and need a quality inspection before a large shipment leaves China, consider a third-party inspection service. This is particularly important for children's apparel, where compliance with flammability and content regulations (US CPSC, EU REACH) is a legal requirement, not just a nice-to-have.
For Shopify sellers who want sourcing and fulfillment handled in one place — from the initial 1688 supplier search through to international shipping — Piratify is built specifically for this workflow, with native support for 1688 alongside Taobao, Tmall, and other Chinese platforms.
Most 1688 suppliers communicate via the platform's built-in chat (旺旺 / Wangwang) or WeChat. Use translation tools — Google Translate or DeepL — to draft your messages in Mandarin. Even imperfect Chinese is received far better than English-only messages.
Key questions to send in your first message (in Chinese):
Suppliers who answer these questions clearly and quickly are the ones worth building a relationship with. Those who respond with vague pricing and stock photo links are best avoided at the apparel stage.

No. A Chinese XL in clothing is typically closer to a US Medium or Large depending on the brand and cut. Chinese garments are generally cut slimmer, with narrower shoulders and shorter sleeve lengths than Western-fit equivalents. Always compare flat-lay centimeter measurements rather than relying on letter size labels from 1688 listings.
Request a physical sample before committing to any bulk order. Ask the supplier for the fabric's fiber composition and GSM (grams per square meter), then evaluate the hand-feel, stretch, and color consistency in person. Wash the sample once and re-measure to check for shrinkage. Listing photos — even high-quality ones — are not a reliable quality indicator on 1688.
MOQs vary widely depending on the supplier and style. Some factories require 100–500 units per colorway; others — particularly trading companies rather than direct manufacturers — may accept orders as low as 10–30 pieces. MOQs are almost always negotiable, especially for new buyers willing to pay a slightly higher per-unit price on the first order. Always clarify MOQ per size run vs. per style, as these can differ significantly.
