🪡 THE HISTORY OF SIZING

From Royal Tailors to the Fitting Room Blues

Before there were numbers stitched into clothing tags, garments were made to fit you.
Centuries ago, every piece of clothing was created by hand—tailored for a single person’s exact shape. During the reign of Queen Elizabeth I, fine dresses were crafted by court seamstresses who measured every inch of her silhouette. Fabric was precious, and the notion of “fit” was intimate—an art form meant to highlight individuality.

Clothing wasn’t mass-produced. It was a reflection of status, care, and personality. The tailor knew the wearer; the wearer knew the maker. Each garment told a story.


When “Standard” Sizing Took Over

Everything changed in the Industrial Revolution. Factories were born, and clothing shifted from custom craftsmanship to mass production. In the early 1800s, military uniforms were the first to be standardized—men were measured in groups, averaged out, and issued garments in predetermined sizes. This “efficiency model” soon spread to women’s fashion.

But women’s bodies were never so easily categorized.

In 1941, the U.S. government and the Department of Agriculture launched a massive survey of women’s measurements to create a “national size chart.” The idea was to find statistical averages that could guide dress manufacturers.
Yet, even after studying over 15,000 women, the data was flawed—most participants were white, middle-class, and young. Their proportions didn’t represent the diversity of women’s shapes, ethnicities, or ages. The result? A “standard sizing” system built on exclusion from the very beginning.


The Rise of Vanity Sizing

As decades passed, clothing brands realized that smaller numbers made women feel better—so a size 12 in the 1960s quietly became a size 8 today. What began as flattery turned into confusion. There was no universal system anymore—each brand made up its own.
The promise of a “perfect size” became a moving target, leaving generations of women frustrated in fitting rooms, wondering why their bodies didn’t seem to “fit.”

But it wasn’t your body that changed.
It was the system.


The “Plus Size” Label Appears

By the 1980s, as fashion marketing grew more image-driven, sizing expanded—but not in a way that empowered. “Plus size” became a label meant to separate rather than include. Entire sections of stores were cordoned off, creating a false divide between “regular” and “other.”
Instead of celebrating real diversity in shape, the industry doubled down on a narrow beauty standard—fueling insecurity and waste. Millions of garments were returned, discarded, or destroyed because “standard” sizing didn’t fit real people.


The New Era: Fit Technology & Customization

Today, we’re entering a new chapter. With 3D body scanning, digital pattern-making, and made-to-order production, clothing can once again be made for you—not a made-up size chart.
MySizeology is part of that evolution.

Through a simple 10-second body scan, we collect over 70 data points—20% more accurate than a tailor’s tape measure. Your custom pattern is then used to create clothing that fits perfectly to your body and your preferences—whether you prefer a certain pocket style, inseam, fly type, or thread color.

It’s fashion returning to its roots:
personal, sustainable, and empowering.


Why Fit Still Matters

When clothing fits, you don’t think about it.
You walk taller. You smile bigger. You see yourself—not the tag.

At MySizeology, we believe style has no size. We’re rewriting history—one custom pair of pants, one confident woman at a time.
