Mine is on the left as well, but there must be some pretty good knock offs out there if it's hard to tell! I think the bday dress is just adorable, but the buttons fell lose on mine the day after I got it. Mind you, this was a couple years ago so AG might have fixed up this problem since then, but I remember a couple other members having this same issue as well.

My Kit has a body tag and I just adore her... she's such a cute doll! Can't beat the easy to fix up hair either. Hope you get her soon!
