Well, being someone who recently got Addy, I have noticed that she and kirsten are like birds of a feather. Their clothes just interchange so easily! I also am one who ends up pairing my dolls up with buddies. Like the obivous, Sam and Nellie, Lizzy and Lissy, and for some reason my AGoT 04 Kaede and Molly (which is kinda interesting considering Molly is WWII and Kaede is Japanese... but they've always just fit together). Even when I got Jess she just didn't fit with Kirsten and so Kirsten has just been kinda on her own (Jess doesn't mind it for what ever reason in my head). Then Addy showed up... and wham they've just got this friendship in my head (haha I'm mumbling)

My point is the dolls go so well together! I'd definatly recommend getting Addy with Kirsten. I have always been a person who likes getting more dolls than accessories. I like to collect slowly and only focus on the outfits and accessories I really like.

There has only been one doll I have wanted to complete a collection for and that is Nellie... so you can see where my opinion comes.

I think if you get Addy and Kirsten together you'll still have a good bond time with them because they just seem to go together. JMO!
