i like it, but though i'm into more typically old fashioned names, i'm not a fan of the nickname
Dottie. it feels a little awkward to say?
Dori/Dory is a nice nickname imo, it's cute and feels more natural.
i like
Dorothy Irene a lot (
Irene is one of my favs), but
Dorothy Elise and
Dorothy May are really nice.
Eloise is a little too much syllables/too rhymey, but not bad at all.
