I sold my Bitty Twins (the worst mistake I've ever made, believe me. I love the first edition BT's so much more than the second edition BT's because I absolutely HATE baby dolls with long-er hair, like the second edition Girls.
I also don't like it that the focus has switched more from Boy and Girl to Girl and Girl. You notice that there are two coordinating Girl and Girl outfits, one Boy and Boy and one Boy and Girl, besides their 'Meet' outfits. I hate that.
