I love the name Kimberly, but I hate this variation. It looks tacky, and extremely modern. I would suggest Kimber as a first name, and Leigh as a middle name to go with it.
It seems like a really boring name only made worse by the longer variation on the spelling. God help any poor child who's going to spend at least 20 years of her life correcting people on how to spell it.
Well I've been using this name for 19 years now and it's not at all complicated really. As for it being tacky? I think not! I'm proud to have this name as it's not the usual run of the mill name. I've yet to come across another person with this name. So I guess you could say it's unique. HA!
