All about

What is EyeFitU?

Every brand (and every region) has a different size, a different cut, and basically a different fit. Consumers are rightfully confused as to what clothes are going to fit them. EyeFitU is solving the problem of unsustainable fashion - with outrageous return rates, products not fitting, products being thrown out - by making sure each user is ordering the right fit.

They call it “Size-as-a-Service.” Using their patented technology, the consumer simply inputs their height, weight, and age, and their algorithm predicts their fit size with over 95% accuracy. Then the consumer gets a recommended size, which showcases where the garment may fit from loose to tight on the bust, waist, and hips, for tops, and waist, hips, and length (optional), for bottoms. Having received this information, the consumer gets to choose whether they want their garment to be tighter fitting or looser fitting. 

You can even, working with their developers, have the correct size automatically populate when the consumer lands on the product detail page, thus making sure they no longer have to choose their size.

Their technology integrates into mobile apps, smart mirrors, and you can even use a QR code.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

What makes EyeFitU different than competitors?

EyeFitU is using regional statistical data to predict fit based on 3 input metrics. Competitors may use a photo upload, which can have a lower adoption rate due to A) not having a photo on hand and/or B) not wanting to upload a photo. So instead, simply list your weight, height, and age group, and your size is predicted using dozens of data points and their vast database of historical data.

Because of the simplicity on the front-end, their tool is very easy to set up, and doesn’t require (really) any ongoing effort on the merchant's part.

What metrics is EyeFitU going to improve for my Ecommerce store?

EyeFitU affects both conversion rate and return rate, which ultimately leads to a better customer experience. They’ve seen an average conversion rate increase of 15%, Average Order Value (AOV) increases by an average of 45%. Revenue goes up, size widget usage increases, and returns decrease by an average of 55%.

These are huge metric improvements for fashion brands.

Who has to manage EyeFitU and how long does it take to setup?

To get set up, you send your body measurement size chart to their team, they determine how to best integrate you - for Shopify, it’s their app which is nearly completely self-serve, for other platforms it may be a javascript snippet or Google Tag Manager integration. It can take anywhere from a couple hours to a couple days to get setup, and for larger brands you may take a few weeks in development and testing.

You also will integrate your Google Analytics so that they can set up events and showcase results within Google Analytics.

From there, the platform is nearly completely running on its own. The only thing you need to do is send or upload new size charts for new products.

One thing they’ve noticed with some clients is that in using their technology, you sometimes learn that your size charts are not as accurate as you thought they were, so they create a very helpful feedback loop to get information back to you (the brand) to help you understand the accuracy of your size charts.

Once you’re up and running, you get monthly reports with your breakdown of male/female and their sizes, so that you can better understand how to merchandise your products moving forward. This leads to better inventory procurement and less product left sitting on the shelves.

Is EyeFitU right for my store?

EyeFitU is naturally for fashion and apparel merchants - Athleticwear, lingerie, high fashion, fast fashion, bikinis, menswear, dresses, pants, and really anything clothing size related, especially for tops and bottoms. They also have a prototype version for shoes, which will turn into a full-fledged product soon.

You can use the self-serve tool as a Shopify brand with as few as 1,000 visitors a month, but mostly their tool is for higher volume merchants. Great for high SKU merchants and merchants with high product turnover. This tool becomes a must-have for brands doing over $50k/month, as it will simply blow up your revenue.

EyeFitU isn’t for starting stores. Instead, focus on getting your first few hundred customers, and once you’ve got problems with sizing, returns, etc., you then clearly will be ready for a tool like EyeFitU.

For non-Shopify brands, there may be an integration fee starting at $1,000 and going up to $10,000 for enterprise brands, with additional costs for any additional integrations. Ask their team for more details.
