How to evaluate an sizing solution
Sizing platforms make similar promises and differ in the operational details. These are the criteria we recommend checking with any vendor, including us:
- Dataset composition, which populations the model is trained on, and how representative that is of your selling market.
- Data location, where your customers' data physically resides and what contractual guarantees (DPA, sub-processors) the vendor provides.
- Functional scope, size recommendation only, or also virtual try-on and product configuration.
- Integration model, what is required from your technical team, and how long until you go live.
- Supported categories, how the model performs on technical garments, plus and petite sizes, and made-to-measure products.
- Measuring results, how impact on returns and conversion is calculated, and whether a trial period is available.
The vendor landscape
Alongside Sizebay, the fashion sizing market also includes True Fit, Fit Analytics and Virtusize.
