Universal Sizing: A Better Way to Shop

What does it mean to have universal sizing—and why should it matter to you?

When you’re working with clothing from thousands of different brands, all sizing their pieces differently—and then layering in decades of changing standards—it starts to matter. When vanity sizing exists, it matters. When brands create their own arbitrary sizing systems, it matters.

Sizing, as most people know it, isn’t consistent. It’s not even reliable.

At Diversity, addressing this has been one of the most labor-intensive processes we’ve taken on. Every single item that comes through our doors is physically measured before it ever hits the floor.

From there, we built our own system.

We started by creating a universal sizing chart: a simple, easy-to-understand scale from 1 to 10—1 being the smallest, 10 being the largest. Then we developed a tool that allows you to input your exact measurements and receive a corresponding number within that scale.

So what does this actually do for you as the customer?

It removes guesswork. It removes inconsistency. And more importantly, it removes the need to think about gender when shopping.

Instead of navigating “men’s” versus “women’s” sections or trying to decode brand-specific sizing, you can walk up to any rack in the store, find your number, and know it will fit your body.

It creates a level of uniformity that goes far beyond traditional labels like XXS–2X—and opens the door to shopping based on what you actually like, not what a tag tells you.

We’re not trying to reinvent the wheel. We’re just making it simpler—and a lot more interesting.

You never know—you might be a “small” after all.
