Fit & Sizing

Body measurements, sizing systems, and fit technology

Clothing sizes are marketing artifacts, not measurements. A size 8 in one brand might fit like a 12 in another. This inconsistency drives 70% of online clothing returns—creating waste, frustration, and cost. Our fit and sizing coverage explains why sizes are unreliable, how to measure your body correctly, and how technology is finally making body-aware sizing practical.

Key Terms

Vanity Sizing

The practice of labeling garments with smaller size numbers than their actual measurements to make customers feel better about their purchases.

Size Block

A brand's base pattern from which all sizes are graded. Different brands use different blocks, causing size inconsistency.

Made-to-Measure

Garments made by adjusting an existing pattern to your specific measurements, offering better fit than off-the-rack without full bespoke construction.

Bespoke

Garments made from scratch using a pattern created specifically for your body, typically through multiple fittings.

Frequently Asked Questions

Why don't clothing sizes match between brands?

There's no universal sizing standard. Brands create their own size systems based on their target customers, adjust sizes for marketing (vanity sizing), and change sizing over time. A size label is a marketing tool, not a measurement.

How can I find my size when shopping online?

Don't trust size labels. Instead, measure your body accurately (bust, waist, hip, shoulder width, inseam) and compare to the garment's actual measurements when provided. Body scanning technology is making this easier by capturing your dimensions and matching them to garments.

What's the difference between made-to-measure and bespoke?

Made-to-measure adjusts an existing pattern to your measurements—efficient and cost-effective. Bespoke creates a new pattern specifically for your body through multiple fittings—more expensive but handles unusual proportions better.
