A 500-piece run of lace bodysuits came back with every cup seam puckered and the elastic at the leg openings rolling after the first wash. The factory had followed the tech pack to the letter, but the pack specified a stretch lace by weight only, 180 g/m², with no mention of elongation at break or recovery after 10 cycles. The fabric passed the weight check and failed the garment. That is the gap between a drawing and a spec, and it is where most private label programs lose their margin. You are here because you need a factory that can close that gap, not just sew to a sketch.
What the Tech Pack Must Carry Before You Send It
The fastest way to sort serious factories from sample shops is to send a tech pack that demands measurable fabric properties, not just a swatch photo. A lace bodysuit lives or dies on two numbers: elongation at break and elastic recovery, both tested per ASTM D4964. If your pack only lists weight and composition, you are handing the factory permission to choose any stretch lace that looks right, and you will discover the difference at the fitting, not at the quote. State the minimum elongation, say 120% in the warp direction, and the recovery limit, say 95% after 10 cycles at 50% extension. That single paragraph in your pack filters out most low-cost suppliers before they quote.
The pack must also carry the point of measure (POM) for the elastic tension at the leg and arm openings, specified in grams per centimeter, not just “comfortable fit.” A factory that cannot commit to a tension number in writing is not ready for a multi-size run.
How to Read a Factory’s Response to Your Pack
When you send a pack with those ASTM numbers, watch the response time and the questions. A factory quoting within 24 hours with no technical questions is quoting against a stock fabric, not sourcing to your spec. That is fine for a fast-fashion test, but it is a liability for a repeatable program. The factories worth visiting will come back in 48 to 72 hours with a substitution list: your spec against their available lace, with the elongation and recovery numbers for each option, and a note on minimum order quantity (MOQ) per color. If they quote a price per piece without quoting the fabric MOQ separately, ask for it. A 300-piece garment MOQ paired with a 1,000-meter lace MOQ means you are paying for dead stock or the factory is cutting from a shared roll, which kills consistency. Insist on a line item for fabric yield and waste factor, usually 8 to 12% for a cut-and-sew lace garment. That number tells you if the pattern maker has actually nested the markers or is estimating.
The Sourcing Visit: What to Inspect in the First Hour
If the quote and the technical response hold up, the next step is a visit, and the first hour tells you most of what you need to know. Walk straight to the cutting table. Look for a fabric relaxation station. Stretch lace knitted on circular machines has residual torque, and if the factory does not let the rolls relax for 24 to 48 hours before cutting, the bodysuit will twist on the body after one wash. Ask to see the spreading log. If they cannot show you a log of when the fabric was pulled and when it was cut, the relaxation step is theoretical. Next, look at the elastic attachment. For a bodysuit, the leg and arm openings are typically assembled with a multi-needle chain stitch or a coverstitch. Inspect a sample in production. Pull the elastic gently. If the stitch density is under 12 stitches per inch, the elastic will channel and roll. The stitch count is a spec, not an aesthetic choice, and it belongs in your pack.
Testing Protocols That Prevent the Wash-Roll Failure
The puckered seam and the rolling elastic are both wash-test failures, and both are preventable with a wash protocol written into the pack. Specify a wash test per AATCC 135, five cycles, and require the factory to submit a washed sample before bulk cutting. The cost is minimal, usually $50 to $100 per wash test, and it catches the torque and recovery issues before you own 500 pieces of inventory. For lace specifically, require a snag test per ASTM D3939 on the finished garment, not just the fabric. Lace snags in wear, not in the lab, and a garment snag test reveals whether the seam allowance and the lining choice are protecting the lace or exposing it. A factory that pushes back on these tests is telling you they do not have the in-house lab or the relationships with a third-party lab to run them. That is a red flag for any program over 500 units.
Sourcing Lace Itself: The Mill vs. the Jobber
Your factory may source the lace, but you should understand the supply chain. Lace for bodysuits is typically a raschel knit, and the mills that produce it are concentrated in a few regions. A factory sourcing from a mill will quote a 3 to 4 week lead time for the lace and a higher MOQ, often 500 meters per color. A factory sourcing from a jobber (a fabric broker) can quote a 1-week lead time and low MOQ, but the fabric is often from a discontinued lot, meaning no repeat orders. For a private label program built on continuity, the mill route is the only safe one, even if it raises your initial MOQ. Ask the factory for the mill name and address. If they will not provide it, they are buying from a jobber. This is not always a dealbreaker for a one-off capsule, but it is a structural problem for a brand planning to reorder the same style for three seasons.
The Pricing Structure You Should Expect
A transparent quote separates fabric, trims, cutting, sewing, and finishing. For a lace bodysuit, the lace itself should be 35 to 45% of the FOB cost. The elastic and findings (hooks, rings, sliders) are another 10 to 15%. Cutting and sewing labor is 25 to 35%, and finishing, packing, and polybagging is the remainder. If a factory quotes a single lump-sum price per piece, ask for the breakdown. A factory that cannot break out the fabric cost is hiding either a low-quality substitution or a margin they do not want you to see. The breakdown also lets you pressure-test the quote. If the lace is quoted at $4 per yard and you know the market for that spec is $6, the factory is quoting against a lower-grade fabric. Use the breakdown as a negotiation tool, not just a record.
Managing the MOQ and the First Run
The MOQ for a lace bodysuit is driven by the fabric, not the sewing. A factory may offer a 200-piece sewing MOQ, but if the lace MOQ is 600 meters and the yield is 1.2 meters per garment, you need 240 meters for 200 pieces, leaving 360 meters of dead stock. Negotiate the dead stock. Ask the factory to hold the excess lace in their warehouse for 60 days, allowing a reorder without a new fabric MOQ. If they refuse, consider splitting the MOQ across two colors. A 600-meter lace MOQ split into 300 meters of black and 300 meters of nude gives you two sellable SKUs from one fabric commitment. This is how you turn a sourcing constraint into a merchandising advantage. The first run should also include a 5% oversupply of cut pieces for the factory’s quality control, written into the pack. That 5% is your insurance against in-line rejects, and it costs a fraction of the total order.
The Audit Trail: What to Keep from Every Run
Every production run should generate a file you can hand to a new factory if the current one fails. That file is your tech pack, the approved sealed sample, the wash test report, the fabric test report from a third-party lab, and a production photo log of the cutting and sewing stages. The photo log is the most overlooked and the most valuable. Ask the factory to take four photos per day: the cutting table, the sewing line, the finishing area, and a close-up of the in-line quality check. These photos are your audit trail. If a future run fails, the photos from a successful run show you what “right” looked like, and you can compare. A factory that resists the photo log is a factory that does not want a record. Insist on it. The cost is zero to you and a few minutes a day for them, and it is the single best tool for maintaining consistency across seasons and across factories. Your brand’s continuity is built on that file, not on the relationship with any single factory.

What to send us
If the specifications above match what you are sourcing, send your tech pack to Orange Sea Clothing. If the pack is not written yet, sketches and a reference sample are enough to start — sample development covers the design review, fabric and trim sourcing, pattern making and the first prototype, so you see fit and construction before you commit to a production run.
