Get It Right
How to Measure
Accurate measurements are the key to getting K-fashion right on the first try. Use a soft measuring tape, wear thin clothing, and stand naturally.
Bust
Measure around the fullest part of your chest, keeping the tape level and snug but not tight.
Waist
Measure at the narrowest point of your natural waist, typically just above the belly button.
Hip
Measure around the fullest part of your hips, keeping feet together and tape parallel to the floor.

Insider Knowledge
Pro Tips
Free Size = Small
"Free size" in Korean fashion usually fits US XS-S (Korean 44-55). If you're above US size 4, skip free size items and look for numbered sizes.
Check Flat Measurements
Korean sellers often provide "flat measurements" (laying the garment flat). Double the width measurement for your actual body size. This is the most accurate way to compare.
Fabric Matters
Korean fashion uses a lot of stretch fabric. If the item has spandex/elastane, you can usually stay true to size. For non-stretch (100% cotton, linen), size up.
Buy from US Stockists
Amazon, YesStyle, and W Concept US often have easier return policies than ordering directly from Korea. Worth the slight markup for sizing peace of mind.
