Katie and Leah are twin sisters. WDYTO their names? No idea whether they have middle names let alone what they are. I'm not sure whether these names go together or not.
I think they compliment each other fairly well. Both names aren't my favourite in the whole world. Katie's pretty but fairly commonplace (I'd prefer Kate); and Leah's OK.
I don't think they go together much. Katie is cute but pretty. Leah is more sensible sounding, and somehow doesn't conjure up quite the pretty image for me. Maybe that's because the Biblical Leah was ugly. It's still not the worst twinset out there!
