You sell or source silk sleepwear and robes, but global sizing can still derail conversions and inflate returns. This guide gives YOU a practical framework to build and publish size charts that work across regions. You’ll get clear body vs garment measurements, regional mapping (US/UK/EU/AU), recommended ease for silk fabrics, tolerances for production, grade rules, length options, and fit notes. Use it to brief your team, align your factory, and help customers choose faster with fewer post‑purchase surprises.

Why A Global Size Chart Matters
You operate across multiple markets and channels. If your chart only says S/M/L, shoppers guess and returns rise.
A global chart maps between regions and clarifies body vs garment measurements.
Standardizing inputs (height, bust, waist, hip) builds confidence and increases conversion.
It also streamlines communication with patternmakers and suppliers, including Silk Clothing Manufacturers handling multi‑market orders.
What Body Measurements You Should Publish
Publish the core set for women’s sleepwear and robes: bust, waist, hip, and height.
Add bicep and shoulder breadth for long sleeves and robes.
Explain method: measure over underwear, tape parallel to floor, stand naturally.
Include both inches and centimeters to serve international users and search intent.
Reference ranges (indicative, adjust per brand fit):
- Bust: XS 31–32″, S 33–34″, M 35–36″, L 37–39″, XL 40–42″, 2XL 43–45″, 3XL 46–48″.
- Waist: XS 24–25″, S 26–27″, M 28–29″, L 30–32″, XL 33–35″, 2XL 36–38″, 3XL 39–41″.
- Hip: XS 34–35″, S 36–37″, M 38–39″, L 40–42″, XL 43–45″, 2XL 46–48″, 3XL 49–51″.
How To Map US, UK, EU, And AU Sizes
Offer a direct conversion to stop shoppers from leaving to look it up.
- US 0–2 = UK 4–6 = EU 32–34 = AU 4–6 = XS
- US 4–6 = UK 8–10 = EU 36–38 = AU 8–10 = S
- US 8–10 = UK 12–14 = EU 40–42 = AU 12–14 = M
- US 12–14 = UK 16–18 = EU 44–46 = AU 16–18 = L
- US 16–18 = UK 20–22 = EU 48–50 = AU 20–22 = XL
- US 20–22 = UK 24–26 = EU 52–54 = AU 24–26 = 2XL
- US 24–26 = UK 28–30 = EU 56–58 = AU 28–30 = 3XL
Tell users to pick by body measurements first, then validate with regional mapping.
Which Garment Measurements To Provide
Body measurements drive size selection; garment measurements communicate intended fit.
Publish flat measures per size or provide a size‑M reference plus grade rules.
Key garment points:
- Chest width (1″ below armhole)
- Waist width (natural point; for elastic: relaxed and stretched)
- Hip width (7–9″ below waist)
- Shoulder breadth (HPS to HPS)
- Sleeve length (from HPS or armhole)
- Body/robe length (HPS to hem)
- Belt length and belt‑loop height
- Bicep and cuff opening
Add a “How we measure” note: lay flat, do not stretch, double widths for circumference.
What Ease Works Best For Silk
Silk drape amplifies ease decisions. Plan wearing ease plus design ease.
Recommended ease over body:
- Bias‑cut slip (charmeuse): bust +2–3 cm, hip +3–5 cm, minimal waist; bias adds give.
- Straight‑cut pajama top: chest +8–12 cm for relaxed drape.
- Pajama pants: hip +6–10 cm; specify elastic relaxed and stretched values.
- Kimono robe (wrap): chest +14–20 cm for secure overlap.
- Stretch silk (90/10): reduce ease by 20–30% vs pure silk.
These ranges work across a silk sleepwear gown or a tailored silk Pajama shirt with minor adjustments.
What Tolerances To Set
Tolerances protect consistency without rejecting good production.
Typical woven silk tolerances:
- Lengths: ±1.0 cm (tops), ±1.5 cm (robes).
- Chest/hip width: ±1.0 cm.
- Shoulder breadth: ±0.8 cm.
- Sleeve length: ±1.0 cm.
- Elastic waist: relaxed ±1.0 cm; stretched ±1.5 cm.
- Bias pieces: add +0.5 cm to length; measure after 24‑hour hang.
How To Handle Height And Inseam Variation
Offer length options to reduce alterations and returns.
- Robes: Short 90–95 cm, Midi 110–115 cm, Long 125–130 cm.
- Pants inseams: Petite 70–72 cm, Regular 76–79 cm.
- Sleeves: Regular and +2 cm options.
Publish guidance: choose length by height and preferred coverage.
What Fit Notes Reduce Returns
Fit notes bridge charts and real wear. Keep them brief and specific.
- “Between sizes at bust? Choose the larger for woven silk tops.”
- “Bias‑cut slips relax up to half a size after first wear/steam.”
- “Elastic waist sits mid‑rise; measure at your navel.”
- “Robe overlap is 15–18 cm in your true size; size up for extra wrap.”
- “Pants relax 1–2 cm at hip after steaming—don’t size down for this.”
How Fabric And Construction Affect Fit
Call out fabric behavior so customers set the right expectations.
- 19 momme charmeuse: fluid, body‑skimming; follow chart.
- 22–25 momme: heavier drape, more forgiving at hip.
- Sandwashed silk: suede‑like hand; add +2 cm hip ease.
- Stretch silk 90/10: reduce ease; better for curvier fits.
- French seams/piping add structure; add +0.5 cm at bicep/cuff allowance.
These notes help users compare mulberry silk sleepwear with blended or sandwashed options.
How To Define Grade Rules With Your Factory
Predictable size jumps require documented grade rules.
Baseline woven grade (half‑measure increments):
- Chest/hip width: +2.0 cm per size
- Waist width: +2.0 cm per size (elastic spec included)
- Shoulder breadth: +0.5 cm per size
- Sleeve length: +0.5 cm per size
- Body length: +1.0 cm per size
- Bicep: +0.6–0.8 cm per size
Include a PP sample sign‑off: measured values, tolerances, hang‑time notes for bias.
How To Present Size Charts For SEO And UX
Turn sizing into a trust signal and a ranking asset.
- Publish a canonical “Global Size Chart” page and link it from every product.
- Provide an inch/cm toggle and a mini “Find Your Size” widget (bust/hip/height).
- Add FAQ schema to capture long‑tail (“How to measure for silk robes?”).
- You can also interlink your sizing hub with a Silk Robes OEM Guide to help B2B buyers connect specifications, customization options, and production timelines in one place.
- Use internal anchors for robes, slips, pajama sets, lingerie, and accessories.
- Keep numbers identical across PDPs, emails, and PDFs to avoid confusion.

How To Reduce Post‑Purchase Fit Issues
Proactive guidance lowers returns and boosts reviews.
- Include a measuring guide insert and QR link to your chart.
- Recommend steaming once before judging fit (silk relaxes slightly).
- Offer free exchanges on first order to reduce risk.
- Capture return reasons by body area and feed insights into pattern updates.
What Data To Track And Optimize
Let numbers inform size decisions across markets.
- Size guide clicks vs conversion rate.
- Size distribution sold vs return rate.
- “Too small/too large” tags vs body measurement bands.
- Height/inseam complaints vs available lengths.
These metrics help you set accurate specs for real silk pajamas and adjacent styles.
