I've always quite liked
Dee actually, not really sure why. It most definitely works as a nn for names starting with D and I also feel it could stand on its own as a full name. DeeDee is alright for a nn for someone with the name
Dee or a name starting with D, but I wouldn't use DeeDee as a full name.
