Amazon | Prime Wardrobe Redesign

Improving the Prime Wardrobe shopping service on Amazon website.

Prime Wardrobe is a free service available to Prime members that lets users select up to six items to try on before buying them. The process is pretty simple – users get 7 days to try on the clothes at home. If users like them, they will be charged for the items they keep. If users don’t like them, they can send the clothes back without being charged. 


Most users are unaware of this service because of its low discoverability and popularity. For people who have used this service before, they are unlikely to shop or recommend others to use Prime wardrobe.

The Prime Wardrobe service can potentially bring economic benefits to the Amazon website, especially for encouraging customers to join Prime members and propagating Amazon Essential commodities.
From the users’ perspectives, they have more choices to pay for the commodity they like best, which improves the user satisfaction of Prime members.


What is the current user experience of Amazon Prime Wardrobe?

Heuridtic Evaluation
Heuristic Evaluation

We conducted heuristic evaluation to learn about the procedure of buying items on Amazon Prime Wardrobe and uncovered several usability issues: 

1. The Prime Wardrobe page is hard to find and makes a poor first impression.

Currently, if users want to enter the Prime Try Before You Buy page, they need to first go to the regular commodity search page, then they have to click the Prime Try Before You Buy in the upper right corner of the interface, which is really complex.


2. The searching page does not clearly tell users which items can receive “Prime Wardrobe” service. 

When users want to search a specific item, the recommended commodities, the filter bar and the Prime Try Before You Buy Cart in the upper right corner will distracted, and the “Prime Wardrobe” icon under the commodities are not obvious to users.


3. On the item page, there is too much repetitive and distracted information.

In the specific item page, users easily ignore the prime Try Before You Buy button, which under the commodity information, so that users find it hard to add the specific item to the Prime Try Before You Buy Cart. In addition, some users easily forget to choose the clothing size, and the notification about this omission on the right bar is not obvious.


4. The Prime Wardrobe Cart page is lack of design, and the procedure of changing items is complicated.

There are two different carts, and the Amazon Shopping Cart contains the Prime Try Before You Buy Cart, which will make most users feel confused. In addition, the layout of the Prime Try Before You Buy Cart interface is really chaotic, which can not differentiate the personal information and public common information.


What are users' actual feelings and suggestions for Prime Wardrobe?

Usability Testing
User Testing

We conducted user testing to prove the issues we found out in the evaluation. The primary goal is to evaluate Amazon Prime Wardrobe’s user experience including its degree of discoverability, comprehensibility, efficiency, and availability.

User Testing and Interview Scripts

During the user testing interview, we gave participants two main tasks to finish: shopping on the regular Amazon website & shopping on Prime Wardrobe. We expect to figure out how user experience will change if they choose different shopping ways to purchase clothes.


Task1: Amazon Regular Commodity Purchase

1. You are looking for a jean on Amazon, which you plan to wear to your friend’s birthday party next week.
2. Add this jean to your Amazon Cart.

2. Add this jean to your Amazon Prime Try Before You Buy Cart.

4. Go to Amazon Prime Try Before You Buy Cart and check out items.

What information did we get from user testing and user interviews?

Quantitative Analysis
Quantitative analysis of test results

1. Users are familiar and satisfied with the regular Amazon shopping procedure.

From searching commodities to adding items to cart, users can finish the task independently. However, because there is too much information on the website, the commodity discoverability is much lower.


2. Users have trouble with using the Prime Wardrobe searching function and need instructions. 

&  Users may confuse the Prime Wardrobe Cart with the regular shopping cart. 

The searching procedure on Prime Wardrobe commonly causes confusion. Users can be easily misguided to the general searching page and find it hard to go back to the Prime Wardrobe page. Most users are agitated with this function and need the help of instructions during the user testing.

After clicking on the “Add to Cart” button on Prime Wardrobe, users have no prediction of arriving at a new page they have never seen before. They have to spend longer time checking out items. 


3. Users may confuse the Prime Wardrobe Cart with the regular shopping cart. 

With 10 being “very likely” and 1 being “not at all”, users express there is a low likelihood of using the prime wardrobe to shop or recommending others to use this service.


How might we create a more enjoyable shopping experience with Prime Wardrobe service?

Amazon Prime Wardrobe is a prime service which could potentially attract more customers to join the prime membership and bring economic success to the Amazon website. For one month, we discovered its pain points and opportunities mainly based on user testing results and proposed practical solutions to improve the current user experience.

During the user research, I have learned the effectiveness and accuracy of quantifying user testing feedback. The analyzed data directly leads us to discover the current issues and confirm what we need to refine. After combining the quantitative research result and qualitative data from heuristic evaluation, we were able to make design decisions more comprehensively.

Moreover, during the design implementation, I have learned the importance of following the existing Amazon design system. For example, to improve user experience, we have modified the format of buttons, carts, menus, logos. All these elements need to fit with the overall website design system and take effect to better guide users.
