I think I prefer Scarlet, as it's the colour... However, my first daughter's name ends in a double letter (when it could be 1, but both are accepted, like Scarlet/Scarlett) but then my Elliot only has one, but I didn't mind that as he is male (compared to DD) but now I feel like it would be silly to go with one t, as DD1 would be left out, but 2 ts means that the girls are the same and DS isn't, but that makes sense!
So, Scarlet or Scarlett?
