Natural waistline (narrowest point), usually above belly button.
Around the fullest part of buttocks, legs together.
Inside leg from crotch to ankle (for pants).
⚠️ A Note on Accuracy
Clothing sizes are not standardized by law. Every brand cuts their fabric differently, and "vanity sizing" means sizes have gotten larger over time. A Medium in one brand might be a Large in another.
Best practice: Always check the brand's specific size chart and look for actual body measurements (chest, waist, hips in cm/inches) rather than relying solely on S/M/L or numeric sizes.
Frequently Asked Questions
How do I convert US to UK women's clothing sizes?
For women's clothing: UK Size = US Size + 4. So US 6 = UK 10, US 8 = UK 12, US 10 = UK 14. This applies to dresses, tops, and most clothing. However, some brands may vary, so always check the specific brand's size chart.
How do I convert US to EU clothing sizes?
For women: EU Size = US Size + 30 to 32 (varies by brand). US 6 ≈ EU 36, US 8 ≈ EU 38, US 10 ≈ EU 40. For men's shirts, EU sizes are typically chest measurements in cm. Always verify with the brand's chart.
What do XS, S, M, L, XL mean in clothing sizes?
International letter sizes: XS (Extra Small), S (Small), M (Medium), L (Large), XL (Extra Large), XXL, etc. These roughly correspond to numeric sizes: S ≈ US 4-6, M ≈ US 8-10, L ≈ US 12-14. But there's no universal standard—every brand defines them differently.
What is vanity sizing?
Vanity sizing is when brands label clothes larger than their actual measurements to make customers feel better about wearing a 'smaller' size. A US size 8 today is significantly larger than a size 8 from the 1950s. This makes cross-brand size comparison challenging.
How do I measure myself for clothing?
Key measurements: Chest/Bust (around the fullest part), Waist (narrowest part, usually above belly button), Hips (around fullest part of buttocks), Inseam (inside leg, crotch to ankle). Use a flexible tape measure and stand straight. Measure in underwear for accuracy.
What is the difference between petite, regular, and tall sizing?
Petite is for women 5'4" (163cm) and under—shorter torso and inseam. Regular fits women 5'4" to 5'7" (163-170cm). Tall is for 5'8" (173cm) and above—longer sleeves, torso, and inseam. The chest/waist/hip measurements remain the same; only the length changes.
How do men's shirt sizes work?
Men's dress shirts use collar and sleeve measurements in inches: e.g., 15/34 means 15" collar, 34" sleeve. Casual shirts use S/M/L or numeric sizes. In the EU, sizes are typically chest circumference in cm (e.g., EU 50 = 100cm chest).
What is the difference between US and Asian clothing sizes?
Asian sizes (Japan, Korea, China) typically run 1-2 sizes smaller than US sizes. A US Medium might be an Asian Large or XL. Many Asian brands provide body measurements in centimeters, which is the most reliable way to find your fit.
How do I convert jeans sizes between countries?
Jeans use waist and inseam in inches (e.g., 32x30 = 32" waist, 30" inseam) in the US. UK jeans use the same system. EU jeans may use cm or a single number. Key conversions: US/UK 28 ≈ EU 38, US/UK 32 ≈ EU 42, US/UK 36 ≈ EU 46.
Should I size up or down when between sizes?
It depends on the garment. For fitted items (blazers, dress shirts): size up for comfort. For stretchy items (t-shirts, leggings): size down for a snug fit. When in doubt, check if the brand's fabric has stretch (elastane/spandex) and read customer reviews about fit.
