Trying to add additional drop down options (size) within the product page.

On our product pages, I need to add a size drop down for "Tops" and a size drop down for "Bottoms". I am not able to do this in the "Classic Editor". If I switch to the "New Editor", I can add different options, but when I go to save the page, I get "Cannot Save Product An unexpected error occurred. Please try again later". Any thoughts on this? Thanks, Nick
