A 12% rework rate on a 500-piece lace bodysuit order is not a quality failure; it is a specification failure. The factory followed your tech pack exactly, but your tech pack did not specify the lace stretch recovery under repeated wear, the seam allowance on the scalloped edge, or the AQL for skipped stitches on the mesh. Every one of those omissions is a decision the factory made for you, and most mid-size China factories will choose the cheaper or faster option. You can fix this before sampling, but only if you know which measurements and standards to put in writing.
What to Specify in Your Lace Bodysuit Tech Pack
Lace bodysuits are high-risk garments because they combine three elements that rarely sit in harmony: stretch, opacity, and delicate fabric edges. If your tech pack only lists the fabric name, color, and basic measurements, the factory is guessing on everything else. To avoid the rework cycle, your tech pack must specify:
Lace Fabric Specifications
- Lace type and pattern (e.g., Chantilly, Guipure, stretch lace, eyelash lace) with a clear photo reference and a minimum 5cm swatch mailed to the factory.
- Stretch percentage and direction — not just "stretchy lace," but "60% stretch in the horizontal direction, 10% in vertical." The pattern needs this to calculate negative ease.
- Stretch recovery — specify that the lace must return to original length after 50% stretch held for 30 seconds. Cheap lace loses shape after one wear; this test catches it.
- Opacity rating — "full opacity with single layer" or "requires lining." If you do not specify, the factory will use a single layer to save cost, and your customers will see through it.
- Weight (GSM) — e.g., "120 GSM ± 5%." This controls how the lace drapes and whether it snags easily.
- Color fastness — specify "Grade 4 minimum for washing and rubbing (AATCC 61)." Lace color bleeding into white mesh lining is one of the most common rework issues.
Mesh and Lining Specifications
- Mesh type — "power mesh," "soft mesh," or "stretch tulle." Each behaves differently in production.
- Mesh weight and opacity — "80 GSM, 95% opacity" is different from "60 GSM, 85% opacity." The factory will not guess correctly.
- Mesh color — if the mesh is a different color than the lace, specify the Pantone code and whether the mesh is visible through the lace pattern.
- Lining placement — "full front lining, open back" or "lining only in bust area." Diagrams help here.
Elastic and Trims
- Elastic width and stretch — "1/4 inch picot elastic, 80% stretch, recovery 95% after 50% stretch." Picot elastic is standard for bodysuits, but the stretch percentage changes the fit dramatically.
- Elastic placement — specify whether elastic is topstitched, zigzag, or coverstitched onto the lace. Each method looks different and stretches differently.
- Hook and eye closure — specify the number of sets (e.g., "3 rows x 2 columns"), the color, and whether it is sewn on with a bar tack or straight stitch.
- Snap closure — specify "metal snap, size 0, nickel-free" and whether it is visible from the outside.
Stitching Specifications
- Stitch type per seam — "4-thread overlock on side seams, 2-needle coverstitch on hem, single needle lockstitch on lace appliqué."
- Stitch density — "14 stitches per inch" is standard for lace, but if you do not specify, the factory may use 10 SPI, which looks cheap and skips easily on mesh.
- Thread type — "textured polyester thread, color matched to lace." Cotton thread on stretch lace will snap.
- Seam allowance — "3/8 inch on side seams, 1/4 inch on lace edges." Lace is often joined with a flat fell or lapped seam to avoid bulk; specify which.
- Topstitching — if topstitching is required, specify the distance from the edge (e.g., "1/16 inch from scalloped edge").
Scalloped Edge Handling
This is where most lace bodysuit rework happens. The scalloped edge is the signature feature of lace, but if the factory cuts it wrong, the garment is ruined. Specify:
- Whether the scalloped edge is the finished hem or if it is folded under. Most bodysuits use the scallop as the hem, but you must say so.
- How the scallop is finished — "raw edge, no binding" or "narrow hem following scallop contour."
- Whether the scallop is cut to follow the lace pattern or cut straight. If the factory cuts straight, the scallop design is lost.
- The seam allowance at the scallop — "0 inch; scallop edge is the finished edge."
Measurements and Fit
- Body measurements with ease — not just "bust 34 inch," but "bust 34 inch with 2 inch negative ease for stretch fit." Lace bodysuits rely on negative ease; if the factory adds positive ease, the garment sags.
- Grade rules — specify how much each measurement changes between sizes. "Bust grades 1 inch per size, waist grades 3/4 inch per size" prevents the factory from using a standard grade rule that does not work for stretch lace.
- Crotch length and snap placement — "crotch length 24 inch from waist to snap, snap centered 1 inch from front edge." Crotch fit issues are the number one return reason for bodysuits.
- Torso length — measure from high point shoulder to crotch, not just center back length. Torso length determines whether the bodysuit pulls down at the shoulders.
Labeling and Packaging
- Label placement — "care label sewn into left side seam, 2 inch from hem."
- Label content — specify fiber content, country of origin, and care instructions exactly as they must appear.
- Hangtag attachment — "hangtag attached with plastic loop to left side seam, not through lace." If the factory punches a hole through the lace for the hangtag, that garment is a second.
- Folding and polybag — "fold bodysuit tissue-paper wrapped, place in individual polybag, 24 pieces per export carton." Lace snags in transit if not protected.
Quality Standards and AQL
- AQL level — "AQL 2.5 for major defects, AQL 4.0 for minor defects." If you do not specify, the factory may use AQL 4.0 for everything, which allows more defective pieces.
- Defect definitions — list what counts as a major defect (e.g., "skipped stitch over 1/2 inch," "lace run over 1 inch," "color mismatch between lace and mesh") and what counts as minor (e.g., "loose thread under 1 inch," "minor wavy seam").
- Skip stitch limit — "zero skipped stitches on elastic application; up to 2 skipped stitches per garment on non-stress seams, self-repaired."
- Color matching tolerance — "Delta E ≤ 2.0 between lace and mesh." This is a measurable standard; do not rely on "looks close enough."
Testing Requirements
- Stretch and recovery test — "garment must stretch 20% in bust and hip and return to original size within 5% after 5 cycles."
- Wash test — "5 home wash cycles, Grade 4 colorfastness, no lace distortion."
- Bursting strength — "minimum 30 psi at bust." Lace and mesh are weak; this test prevents seam blowouts.
- Snap pull test — "snap must withstand 15 pounds of pull force."
Common Tech Pack Mistakes That Cause Rework
Even with the specifications above, brands make predictable mistakes that lead to the 12% rework rate. These are the ones I see most often:
1. Leaving Stretch to the Factory’s Judgment
If your tech pack says "stretch lace" without a percentage and direction, the factory will buy whatever lace is cheapest and closest in color. That lace might have 30% stretch when you designed for 60%, and the bodysuit will not fit. You must specify stretch in numbers, not adjectives.
2. Not Specifying Negative Ease
A bodysuit is not a t-shirt. It relies on negative ease (the garment is smaller than the body) to stay in place. If your measurements do not account for this, the factory will produce a garment that fits like a loose tank top. Write the body measurements and the ease separately so the factory understands the fit logic.
3. Ignoring the Crotch
The crotch is the most functional part of a bodysuit and the most ignored in tech packs. If you do not specify crotch length, snap placement, and whether the crotch is lined, the factory will guess based on a standard they use for other clients — and that standard may not match your target customer’s body.
4. Assuming the Factory Knows Your Brand’s Quality Level
A factory that makes fast fashion and a factory that makes premium lingerie both produce "bodysuits," but their standards are different. If you do not specify AQL, defect definitions, and testing requirements, the factory will default to their usual standard, which may be lower than yours.
5. Not Mailing Physical Swatches
Photos lie. A photo of lace cannot communicate hand feel, weight, or opacity. Mail at least a 5cm swatch of every fabric and trim to the factory and reference it in the tech pack. This costs you $10 in postage and saves you thousands in rework.
How to Structure the Tech Pack Document
A tech pack is not a single page; it is a set of pages, each covering a different aspect of the garment. For a lace bodysuit, I recommend this structure:
- Cover page — style name, style number, season, designer name, date, revision number.
- Technical flat sketches — front, back, and detail views (crotch closure, lace edge, strap attachment).
- Bill of Materials (BOM) — every material with supplier, color, width, weight, and quantity per garment.
- Measurement spec sheet — point of measure (POM) diagram with numbered arrows, measurement table with grades, and ease notes.
- Construction details — seam types, stitch types, SPI, thread, and diagrams of tricky areas (scallop edge, snap attachment).
- Labeling and packaging — label artwork, placement diagram, polybag and carton specs.
- Quality standards — AQL, defect list, testing requirements, and color matching tolerance.
- Revision history — every change logged with date and reason.
What to Do When the Sample Comes Back Wrong
Even with a perfect tech pack, the first sample will have issues. The difference between a 12% rework rate and a 2% rework rate is how you handle those issues. When the sample arrives:
- Check it against the tech pack, not against your memory. Open the document and go line by line. If the factory deviated, note it.
- Fit the sample on a real body, not a mannequin. Lace behaves differently on a moving body. Check for pulling, gaping, and whether the snap stays closed when the wearer sits.
- Wash the sample once. Lace and mesh can distort or bleed after one wash. Better to find out now than after 500 units ship.
- Write a clear, numbered comment list. Do not say "the lace looks wrong." Say "Lace stretch is 35%, spec is 60%. Replace lace with swatch-approved fabric." The factory cannot fix what you do not define.
- Request a second sample (top of production sample) before bulk starts. This is your last chance to catch issues. Do not skip it to save time.
The Cost of Getting It Right vs. Getting It Wrong
A tech pack that specifies everything I have listed takes longer to write — probably 8 to 12 hours for an experienced designer, more if you are learning. That time is not a cost; it is an investment. A 12% rework rate on a 500-piece order at $12 per piece costs you $720 in lost product, plus the time to negotiate with the factory, plus the delay to your launch. A complete tech pack costs you a day of work and prevents all of it.
If you are not confident in your ability to write these specifications, hire a technical designer or a sourcing agent who understands lace garments. The fee for that service — usually $200 to $500 for a tech pack — is less than the cost of one rework cycle. And if you are working with a factory that pushes back on detailed specs, that is a signal to find a different factory. Good factories welcome detailed tech packs because they reduce arguments and rework on their end too.
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.
