Read guideWhy Clothing Sizes Are Broken
A size 8 at Zara is a size 12 at Uniqlo. Your "medium" from one brand might be an "extra large" at another. Size labels aren't measurements—they're marketing tools that have drifted over decades.
70% of online clothing returns are due to fit issues. That's billions of dollars in wasted shipping, packaging, and consumer frustration. The problem isn't you—it's the sizing system.
Understanding why sizes don't work is the first step toward finding clothes that actually fit your body.
How to Find Your Size
Stop relying on size labels. Here's what actually works.
Measure Your Body
Take accurate measurements of your bust, waist, hips, shoulders, inseam, and rise. These are your reliable data points—not size labels.
Measurement guide →Compare to Garments
Look for brands that provide actual garment measurements (not just size charts). Compare your measurements to the garment specs.

Why Clothing Sizes Don't Exist
Sizes are marketing artifacts, not measurements. Vanity sizing, brand drift, and the reality of human variance make labels unreliable.
How to Measure Your Body (Most Guides Are Wrong)
Most guides skip the basics: posture, tape position, and consistency. This shows how to measure so results repeat.
Made-to-Measure vs Bespoke vs Custom
Made-to-measure adjusts a base pattern. Bespoke builds from a personal block. Custom toggles details. Choose based on use and budget.
Why Online Clothing Returns Are So High
Returns are mostly fit failures. They cost margin, create waste, and annoy customers. Better sizing reduces all three.
How AI Body Scanning Works Using Only a Phone
A short pipeline: capture, mesh, landmarks, and pattern mapping. Built to run with privacy in mind.
3D Body Scans vs Size Charts
Charts assume averages; bodies aren't average. Scans capture slope, rise, and asymmetry that charts miss.
Why Virtual Try-On Isn't Enough
Seeing a garment on an avatar helps, but without body data and pattern mapping, fit risk remains.
From Video to Perfect Fit: Digital Tailoring
Digital pipelines connect capture to pattern changes. Humans stay in the loop for quality and taste.
Why Clothes Used to Last Longer
As production scaled up, fabrics got thinner, construction got cheaper, and care habits changed. We unpack what quietly shifted—and how to buy pieces that will actually stay.
The Psychology of Fit
Fit drives attachment. Pieces that move with us become identity—worth designing for.
Tailoring Isn't Old-Fashioned
Tailoring stalled because scale was hard. Digital capture and pattern automation bring it back.
Designing for Bodies, Not Trends
Trend churn ignores real bodies. Body-first design builds longer-lived wardrobes.
