The first three Barbies I ordered arrived -- a day early even -- so I unboxed them and took some photos for you all. I apologize for not being much of a photographer.
Here's the packaging. The tall one is practically touching both the top and bottom of the plastic.
Didn't get a good shot of this, but the back of the packaging shows three guys along with all 21 stand-alone dolls currently shown on Mattel's site. (Not shown: the 12 other dolls which also come with two extra outfits each.)
Here they are with the front plastic removed. Unboxing was rather tricky, as the plastic was sandwiched between two bits of cardstock in a couple places. Thus, the sheer destruction of the packaging. (I don't collect or preserve packaging myself, but if you do, be warned.) Figures were attached to the cardstock with the little plastic cord things at ankles and waist, and the head was attached with two more (with hair also held to cardstock with weak elastic in some cases).
Better head shots. The petite one does not photograph well; I suspected she had the darkest skin tone of the new releases, but according to the booklet that came with my order, #20 (Fancy Flowers) may even be a shade darker.
Here they are in a shot with a random Barbie picked from my existing collection; I don't know if that Barbie is representative of the typical modern Barbie body or not. The tall and curvy ones stand flat-footed; the petite still has the high-heel-style foot.
Petite is almost a head shorter. I'll mention here that none of the new body types are articulated at knees, elbows, waist, etc. Also, the outfits that came with these were all easily removable, with generous expanses of hook-and-loop (except for the tall one's skirt, which has enough give to stretch over her hips).
Tall, standing flat-footed, is barely half a head taller. Note that she has the least waist indent of all the dolls
Curvy is about the same height, and stands flat-footed. She has a slightly bigger bust than Petite and Tall.
