This is an accepted solution.
I checked your website and I have the below comments hopefully it will help
- Adding size chart to your product page
-The pop up that shows the last purchase, it is a bit distracting for your content and it shows the last sale was done 6 days ago, which might not be that convincing to customers
-The reviews at the product page is still empty, I would prefer to not add it now, probably at the next stage of your website when you have sales you can ask customers to write a review and post it.
I hope that my feedback was useful
I think you have added reviews and pop up application, you only have to uninstall it from the Apps section from your shopify admin.
I really recommend digging more into shopify forums, a lot of good ideas out there for Apps, I have found one for you to check it out
