I think the girl's is adorable, with its substantial knit dress, tights, boots, and matching hair tie. The tights don't have a lot of give, so I can imagine them being difficult for a child to manipulate on her own, especially a child of the Twin's target market age. And while the purse is cute, it has a velcro closure on the strap that is simply too small and flimsy to stay closed. I think a little child would easily lose the purse in the course of regular play, so that's a definite flaw. But all in all, I do give the girl's outfit an A-.

But if you can get past that, the whole thing is very well made and the colors and fabrics are great. So, again, an A- grade from me. Our doll LJ is winking at you here in all his cuteness:
