I often dress the girls in similar colours (most of the time without even realising it!) but I don't tend to dress them identically. Just my opinion, but I like them to be individual. I think buying the same thing in different colours is ok, but exactly the same would weird me out if I did it to my kids. Just being totally honest I could do it though I guess, because even though they are 15 months apart, they look totally different, one with dark hair and one with blonde hair.......hmmmmmm You do whatever you want to. You're their mumma and you dress them in whatever you like while you can!
