We are making a clothing store where we want to give the user the option to enter their own measurements.
How do I link a size variant named 'custom' to another page on the site where people can enter their measurements? Exactly like how it is done on this page: https://www.kavvach.com/collections/pink-peacock/products/mint-green-embroidered-draped-lehenga-set
I've been looking at forums and shopify apps but I've found nothing that fulfills this need.
Here's the link to a product on my website: https://fatiz-design.myshopify.com/products/alisha-ombre-shaded-gown
Any help would be great!
Thank you in advance.
