The "Mexican" Body Style
The Mexican body is the easiest body to identify. The defining Mexican
feature is her body is super shiny and has NO Hasbro marks on it at all.
She has longer legs, making her the tallest Jem doll, but since her neck
is a bit shorter, she's not as tall as she could be. The limbs (on
Caucasian dolls) are a pinker tone than regular dolls, plastic and vinyl
seams are often very prominent. Not obvious in the picture, is the shoulders
seem a bit wider/not pushed in as far than those of the regular Jem dolls.
They are lower quality dolls in general, it's quite common for the hands
to be broken off or cracked. Most Mexican's I've seen come with the
smoother wrists, though my Mexican Aja has the knobby wrists (and, not
coincidentally is probably my only loose Mexican doll without hand cracks!)
As for Mexican heads, there are two categories. Both have the shiny
bodies, but some have stamped heads (called Mexican Hybrids), others do
not. Both are considered Mexican dolls, but a true Mexican head (at
least on this page, until it's been disproven) will have no Hasbro markings
and will show signs of poor quality- make up flaws, very pale skin tone
(in Caucasians and Shana), badly stitched hair. I've noticed on all
my non-stamped Mexican doll heads, the hair is sewn sparsely around the
hairline- whereas every other Jem doll has a very dense hairline.
It appears that the Mexican hybrids used left over heads from the Chinese
or Hong Kong factories.
