Release Notes

Release Notes

We are on a mission to make size selection confusion a thing of the past. There is no reason your shoppers should have to fidget with tape measures and a size table or evaluate their body shape vs. that of the clothing model. We developed Fit Advisor to completely remove this confusion so shoppers can exclusively focus on your brand. We will never stop innovating towards that cause.

We are continually taking in feedback from our customers, prospects and end-users, then integrating that feedback into the WAIR product roadmap. In the release notes below you will see the evolution of the best size and fit recommendation solution available today.

March 2021 | Fit Advisor 3.7.0

Released on Mar 3rd, 2021

Many customers request the ability to manipulate the Fit Advisor call to action (“CTA”) without the need to redeploy code on their e-commerce site. Now, Fit Advisor customers can simply login to their WAIR Fit Advisor dashboard ( and modify the Fit Advisor placement and inline recommendation style. Don’t worry, we don’t override any of your custom configurations. If you still want to further customize the Fit Advisor CTA, you can do so.

Improved Performance

After a few months of tuning and optimizing, we reduced the code footprint by ~50%, which results in less data downloading. This minimizes the lag time when a shopper visits a product page and they can see the Fit Advisor CTA.

A New Look to Sizing Feedback Flow

If you’ve integrated WAIR Fit Advisor, you will know that our size alignment process is very unique. It allows us to nail in your sizing strategy regardless of the data you provide in the beginning. It also helps us to get up and running with accurate size and fit recommendations from day 1. While the functionality is amazing, the UX looked MVP (ish).

We have some really amazing ideas to expand the use of this technology, and so we wanted to put a nicer face on it. Now we can honestly say that the size feedback flow UX is as beautiful as the functionality.


In February, we focused heavily on advanced configurations, service performance, and onboarding experience.

February 2021 | Fit Advisor 3.6.0

Released on Feb 3rd, 2021

We spent the better part of January collecting customer and user feedback to create a more compelling Fit Advisor experience. Designed to delight your shoppers and continually improve your core performance metrics.

Intuitive fit preference

We cleaned up the UX for the Fit Advisor recommendation screen to allow shoppers to navigate to alternate sizes based on their unique fit preference.

We received consistent feedback that a “Fit Preference” screen was confusing and therefore causing friction in the shopper journey.  By removing the “Fit Preference” screen and allowing shoppers to see how alternative sizes fit their bodies, we provide confidence in size selection to include fit preference.

Optimized mobile experience

We’ve created optimized input forms and recommendation screens for both mobile and desktop shopping experiences.  The desktop flow takes advantage of the keyboard, where the mobile flow is much more intuitive.  Here are the improvements in the new version:

  • Improved layout for recommendation results on small screens
  • No more mobile keyboard. Touch-screen friendly sliders for input data.
  • Less web data used (smaller bundle and asset files)

Faster load times

We want your shoppers to get their size recommendations with the least friction possible and we know performance matters. 

  • Optimized backend to load Find my Fit button and Inline recommendation placements noticeably faster
  • Improved load times for UI for an overall faster flow to get a recommendation

September 2020 | Fit Advisor 3.0.0

Released on Sep 2nd, 2020

Overview and Main Purpose

  1. Enable Inline size recommendations for higher conversions
  2. Allow for advanced UX configuration for more customization
  3. Launch robust analytics

What’s New

  • Inline Recommendations
    • The BodyBlock Recommend technology predicts the dimensions of the shopper’s body and then recommends the size of any product on the customer’s e-commerce store. Prior to this release, the shopper used to have to open the plugin to review his/her sizes, which was not idea. This release allowed BodyBlock to always show the shopper their size right from the product page, without forcing the shopper to launch the plugin each time.
  • Advanced UX Configuration
    • Each customer has access to their administration dashboard. This allows them to make real time changes to the look and feel as well as the call to action (CTA) of the BodyBlock Recommend plugin on their e-commerce store.
  • Robust Analytics
    • Prior to this, we tracked the conversion rate of shoppers that used the widget vs. those that don’t. We didn’t like this as a conversion metric because those that click a “Find My Fit” button have more intent to purchase than those that do not… so the data is less meaningful. We changed the tracking to create two cohorts. The “Control” cohort never sees the “Find My Fit” button, while the “Live” Cohort does. We then track the conversion differences between the two cohorts to more clearly understand the effect that the BodyBlock Recommend plugin has on site conversion. Good news… we see a 25% increase in conversion percentage of the Live cohort vs. the Control. 😉
