Altea/Antea has always been slender, but in this set linked below, called Kales, she's moving into the downright skinny league, and in another set I just saw elsewhere (a full set, so not available here), called "Liliaceous" (holding a bunch of long-stemmed lillies), she's even skinnier (and with a short-cropped boyish haircut, to boot). Frankly, I was quite happy with her just the way she was, and can't help but worry that she might be on some kind of "model's diet" (the main ingredient starts with "c" and it's the strongest thing you can buy without a prescription . . .). If you want to see her in an unquestionably skinny condition, check out that set; if not, you might want to avoid it.
