Questions to ask both vendors
The most reliable way to compare two vendors is to ask both the same questions and lay the answers side by side:
- Which populations is the sizing model trained on, and how representative is that of my market?
- Where does my customers' data reside, and what contractual guarantees are in place?
- Is the scope size recommendation only, or does it also cover product visualisation and configuration?
- What is required from my technical team to go live, and how long does it take?
- How is the impact on returns and conversion measured? Is a trial or A/B period available?
- How does the model perform on my most difficult categories (technical garments, plus size, made-to-measure)?
Frequently asked questions
What is the difference between We Wear and Sizebay?
Sizebay specialises in size recommendation. We Wear is a modular platform that, alongside sizing (SizeFlow), includes virtual try-on (FitFlow), a 3D configurator (Config3D) and AI product imagery (AI Studio). We Wear is developed in Italy with infrastructure on European servers. For up-to-date detail on Sizebay's offering we recommend contacting the vendor directly.
Can I switch from another solution to We Wear without downtime?
Yes. Integration happens at the JavaScript widget level, so migration touches neither backend nor database. We can set up an A/B test to compare the performance of both solutions before the final switch.
Can I adopt only the sizing module?
Yes. We Wear's modules are independent: you can start with SizeFlow and add FitFlow, Config3D or AI Studio later without redoing the integration.
How can I compare the real-world results of both solutions?
The most robust method is an A/B test on your own traffic, using the same product categories and the same observation window, measuring return rate and conversion rate. We can help you set it up.
