So currently we have it listed that Clorinda is based upon Anstasia Tremaine from Cinderella and Tisbe is based on Drizella. However, when question about the matter on Twitter, Jane confirmed they never intended either of them to correspond with another, nor did they think of them that way. The only Disney thing they took were some wardrobe nods, which would actually indicate the opposite (Tisbe wears pink and has bangs, Clorinda wears green with a green bow). So I am suggesting that we change it to "based on Anastasia and Drizella Tremaine", as opposed to one or the other. This would be more correct and less speculative.
NOTE: Since it is a discussion of two characters, I wasn't sure if it went in the comments for both or not.
