Denim is one of the most beloved and hardest-working categories in fashion—and also one of the trickiest to get right.
The reason? There’s no universal fit formula.
A "size 28" in one style can feel entirely different in another. High-rise, mid-rise, low-rise. Stretch, rigid, vintage cut. Skinny, straight, relaxed. Every variable changes how denim fits—and how customers expect it to feel.
Most fit tech treats denim like any other product: plug in some numbers and hope it fits. But denim isn’t just about measurements. It’s about preference.
One shopper wants that perfectly snug feel. Another wants comfort through the thighs. Someone else is just trying to avoid gaping at the waist.
That’s where Fit Predictor comes in.
By analyzing shopping and return behavior, we understand what customers keep—and why. Instead of guessing how jeans "should" fit, we predict how it will fit and which size they’ll love.
This approach works because it captures what static tools miss:
Denim is a category where sizing mistakes cost more—in customer frustration, high return rates, and lost loyalty.
We’re helping retailers reduce denim returns by 20–30%, simply by giving shoppers better guidance based on what actually works for them.
