I got this Supergirl in a DC vs Masters of the Universe pack with She-Ra. Unfortunatly this is probably one of my least favorite Supergirl costumes. It is a very accurate representation of the character. Supergirl features a white Superman t-shirt, blue skirt, and red cape. The cape is molded in a blowing pose, which throws off the figure balance a little. I still think the white gloves are pretty ridiculous, but that's why I don't really like this costume.
I also think that her legs look oddly spread apart where they come out under her skirt. Supergirl has good articulation that is slightly hindered by her skirt. I'm a little surprised that Mattel didn't pair She-Ra with Wonder Woman.
