The original Gwen Stacy from Marvel Comics
The outfit is the most important part, the black headband, green coat, black turtleneck, and the purple pencil skirt.
For the Mexican Gwen Stacy, if it is possible, the outfit with the red pants and green long sleeve sweater, or the outfit with the diamond-patterned blue mock-neck solid tank top with the green skirt & black headband.
If either Mexican Gwen Stacy is not possible I understand, this is probably impossible either way.
