How to Choose the Right Clothing Size Online | 6sense
Online shopping is convenient, but the wrong size is the most common reason for returns. The solution is simple: accurate measurements in centimeters + size chart + size calculator. European standards EN 13402 and ISO 8559-1 recommend labeling by actual body measurements, not just by letters/numbers.
1) Why measurements are key
Letter and numerical sizes (S, M, L, EU 38, etc.) are a guide. Accuracy comes from measurements in cm, compared with the specific product's chart. Discrepancies between brands and countries (the so-called vanity sizing) make the chart even more important.
2) How to measure yourself correctly
- Bust: around the fullest part; tape measure horizontal.
- Waist: the narrowest part of the torso.
- Hips: the widest part of the hips.
- Garment length: from the shoulder to the desired length.
- Pants: inseam from crotch to ankle.
3) Size systems and conversion
Main systems: INT (XXS–XXXL), EU, IT, FR, UK, US. In Bulgaria, EU is mainly used. Approximate conversions:
EU 38 ≈ UK 10 ≈ US 6–8 ≈ FR 40 ≈ IT 42–44 — varies by brand/cut. Always check the chart.
4) Fabric and fit
- Elastic fabrics (elastane, rib knit): allow for a tighter silhouette; sometimes you can go −1 size.
- Non-elastic (cotton, linen): choose your actual size; for a looser fit – +1.
- Cut: fitted styles require precision; straight and oversized styles offer tolerance.
- Denim – length: inseam 30/32/34 in = 76/81/86 cm.
5) How to avoid mistakes
- Compare only with the specific product's chart.
- For "one size fits all", look at the centimeters in the description.
- Check the reviews – "runs small/large", "elastic/non-elastic".
- See the model's measurements in the PDP.
- When in doubt – order two sizes and return the one that doesn't fit.
