Key Takeaways
- Our large-scale apparel testing shows that there are 5 apparel best practices critical to get right to allow users to confidently make a purchase decision
- Yet our e-commerce benchmark shows that 94% of sites get one or more of these key apparel best practices wrong
- As a result many users won’t have the support they need from the apparel site to proceed with a purchase
Unlike physical stores, where apparel products can be handled, tried on, and physically compared to other products, users shopping apparel e-commerce sites must trust the site to provide accurate representations of their products via images and descriptions.
Indeed, the risk of purchasing an ill-fitting article of clothing is perceived as much greater when shopping online vs. when shopping in person.
When also accounting for things like delivery (and potentially) return times, it is understandable why some users are still hesitant to purchase apparel online.
Therefore, it’s critical that apparel sites provide users with everything they need to make a confident purchasing decision.
Yet our Premium research findings and e-commerce UX benchmark show that 94% of sites neglect one or more key aspects of the apparel-purchasing process.
As a result, some users will abandon an apparel purchase — simply because they don’t have the necessary information to make a purchase decision.
In this article we’ll walk through 5 UX best practices for apparel sites:
- Provide sufficient sizing information (94% don’t)
- Combine product variations into one list item (20% don’t)
- Use buttons for each size variation (63% don’t)
- Provide images of apparel products on a human model (75% don’t)
- Ensure product images have sufficient resolution and zoom (72% don’t)
1) Provide Sufficient Sizing Information (94% Don’t)
For apparel products, selecting the correct size is a highly important aspect of the purchase.
During our large-scale testing of apparel e-commerce sites, we observed that users can be hesitant to purchase a product if they’re not confident in its sizing.
Furthermore, if the correct size is not easily discernible, users may leave the site to find more information, risking that they do not return.
Indeed, during both desktop and mobile UX apparel usability testing, uncertainty around sizing was a common cause for abandoning a product.
Moreover, a product that does not fit — whether it’s a t-shirt or an evening dress — will need to be returned, causing significant hassle and disappointment for the user and strain on the site’s customer support.
Our Premium research findings indicate there are 10 details to get right to ensure sufficient sizing information is provided:
- Provide conventional sizing information
- Provide numeric sizing information
- Provide measurements in both inches and centimeters
- Provide international size conversions
- Provide instructions and tips for taking accurate measurements
- Ensure sizing and measurement information matches the product type
- Include a link to the “size guide” near the size selector
- Ensure the browser “back” button returns users to the product details page
- Include a link to customer service in the size guide
- Consider including measurements of human models
However, our apparel e-commerce UX benchmark shows that 94% of apparel sites fail to provide sufficient sizing information — putting themselves at risk of users abandoning the site.
2) Combine Product Variations into One List Item (20% Don’t)
Apparel product variations — typically colors and sizes, but also some other less-common variations — are key to users’ purchasing decisions.
In the product list, there are two ways to display these product variations:
- Variations are combined into a single list item, with the variations often indicated using swatches below the thumbnails
- Variations are displayed separately, with each variation — for example, shirts in different colors — having its own list item
During multiple rounds of large-scale testing it became clear that there are two major usability issues associated with product variations displayed as separate list items:
- Product lists can become cluttered with variations of products, overwhelming users and making it harder for them to get an overview of the product range
- Many users will struggle to find a particular variation of a product, especially if the variations are spread throughout the product list
In fact, these issues are so serious that they will cause some users to abandon the site.
Therefore, apparel product variations should be combined into a single list item.
When product variations are combined, product lists contain only unique products, which helps users get an overview of products more easily, and users are far less likely to overlook a variation that would suit their needs.
An important prerequisite for combining variations in single list items is that the variations must be linked in the product database.
Therefore to ensure consistency sites that sell products from multiple vendors should post-process product data to link variations of unique products.
Given the severity of this issue it’s surprising that 20% of our benchmarked sites don’t combine variations of products into one list item.
3) Use Buttons for Each Size Variation (63% Don’t)
During our large-scale UX testing, we observed that, when presented as a drop-down menu, participants during testing were prone to overlook the size selector entirely.
Additionally, when users did activate the menu, they were often surprised or disappointed by the sizes available.
In practice, some users who overlook the size selector risk triggering an avoidable error message.
Other users must check to see if their size is available for each variation under consideration — a potentially tedious task that often leads to users simply giving up.
Therefore, instead of using a drop-down with the size options hidden by default, expose the size options by using button-like selectors to help to ensure that these crucial product variations are easily seen by users.
Yet 63% of benchmark sites don’t implement buttons for size selection or don’t implement them correctly.
4) Provide Images of Apparel Products on a Human Model (75% Don’t)
Providing the right kind of apparel product images is essential to users’ ability to understand key visual details and make a purchase decision about a particular product.
During Baymard’s large-scale usability testing across desktop and mobile, we observed that, for apparel products, simple “Cut Out” images of the product against a white background are simply not enough for users to get a sense of their physical qualities.
Instead, apparel sites should provide “Human Model” images on the product details page.
Only with the context provided by seeing the product worn on a human model’s body or face can users come close to an in-store experience, as they’ll gain a better visual understanding of the product and feel more confident in purchasing it.
Without “Human Model” images, it’s left up to the user’s imagination to try to picture how a product might look when worn — which for many users is simply not enough to make them feel confident enough to purchase the product.
Additionally, testing revealed that mannequins or virtually rendered “models” should be considered only as a last resort, as test participants generally responded negatively to such images.
Therefore, real human models should be used whenever possible.
Yet 75% of benchmark sites don’t provide any “Human Model” images, or only provide a single image, which will not be enough to satisfy most users.
5) Ensure Product Images Have Sufficient Resolution and Zoom (72% Don’t)
Our large-scale apparel testing revealed that low-quality images drag down users’ perceptions of products.
In many cases, having low-quality images is almost worse than having no images at all, since users are encouraged to explore a product visually — for example, by a thumbnail in the product page image gallery — but are severely disappointed when they open the larger image and find it’s grainy or pixelated.
For many users it’s perceived as if the site doesn’t care enough to provide them with the visuals they need to make a purchase decision — and thus we observe that many users will instead abandon to try and find this visual information on another site.
In particular, testing revealed 2 key issues with regards to image quality:
- Images couldn’t be zoomed large enough (at least 50% larger than the unzoomed image) to see details
- Images were low-resolution
Either of the issues can cause users to leave the product page.
On the other hand, sites that consistently have high-resolution product images are viewed more positively by users — the site feels more polished and professional, and users are more confident purchasing products that they feel like they’ve sufficiently visually investigated.
Yet our benchmark reveals that 72% of sites don’t provide users with an adequate zoom or resolution for their product images.
Provide Apparel Users with the Information They Need to Make a Purchase Decision
Given how important the above-discussed 5 best practices are for apparel sites — which collectively concern choosing an apparel product variation and being able to visually evaluate the product — it’s striking that 94% of sites get at least one best practice wrong.
As a result, many users will experience significant friction in their evaluation of apparel products, while others will be so frustrated that they’ll leave the site altogether (as observed during testing).
Therefore it’s important to follow the following best practices:
- Provide sufficient sizing information (94% don’t)
- Combine product variations into one list item (20% don’t)
- Use buttons for each size variation (63% don’t)
- Provide images of apparel products on a human model (75% don’t)
- Ensure product images have sufficient resolution and zoom (72% don’t)
An apparel site that meets or exceeds users’ expectations with regards to these best practices will set itself apart from its competitors and provide ample support to users considering apparel products.
