For this costume, I am just going to explore Susan Pevensie's armor that she wears during the much-discussed Night Raid scene and the epic battle, which is amoung my favorites. ;)

The main piece armor is a leather corset, called a cuirass. It is two pieces of hardened leather, each are sealed by piping at the side and laced to eachother. There are straps running across it and up over her shoulders, probably just for decoration (I don't see any reason for them.)

During the nightraid, Susan wears her purple outfit minus the bodice, which is replaced by this cuirass. For this sequence, she wears a leather vest that laces up the shoulders and is open at the sides (see the picture below). I've heard it said that it laces up the neck as well, but if you look closely, it actually just has a slit down the neck, with no closure.

For the battle, she wears the cuirass over a loooovely red dress (which I'll overview later) and a shirt of chain maille.

The chain maille seems to just be a shirt (think pullover)--made of metal. It has 3/4 sleeves that flare slightly as they go down. To protect her neck (and probably to add a little style) there is a gray-blue velvet collar, which could be connected to the dress itself.
