Which one should I choose?

Can someone help? I’m trying to add variation to a parent listing but it’s different in styles - basically different style lashes but I only have color and size option?

Amazon’s variation themes are category-specific, and if “style” isn’t an available option for your category, you may need to use “color” or “size” as a workaround or request a new variation theme through Seller Support. A common approach is to use the “color” attribute to differentiate styles while clearly specifying the actual style name in the title and bullet points. If that doesn’t work, you may need to create separate parent listings for each style.
