Here I would change from "on each side of the costume" to "located on the wearer's left and right hips" so the location is more specific and you don't end up with someone trying to place the hips 2 inches above the knees. This will provide a more targeted location for the GMLs, as well.
I would suggest leaving the curve language out altogether and keep it simple by stating that the plates conform to the wearer's hips, especially if it's a point we aren't especially comfortable nailing down in detail.[*] Both plates have a slight curve both horizontally and vertically to conform to the legs. (This clause I am unsure of. It can be seen in some screen references but not others, it is quite subtle)
I like this but I think we can be a touch more specific, especially with regards to the size of them. The first thing that comes to mind when I hear string is a thin, braided string which I fear could mislead costumers into actually using a braided red nylon string. If we described it as "4 red strap connection pieces made from either leather or leather like material or the same material as the skirts, approximately 1/2 inch/13mm in diameter and approximately 3-4 inches/76-102 mm long" I think that would put us in a much closer ballpark.[*]Top Plate
- The top plate is connected to the bottom of the abdomen via 4 red strings/tassels, looped through holes at the bottom of the abdomen and at the top of the plate.
I would reword the second sentence, for clarity, to say: "The raised details have rounded ridges, are angled downward toward the center of the plate, and run parallel to each other with very little to no space between."
- There are two raised details near the lower left and lower right corner. These details are two parallel rounded ridges and are angled down towards the middle of the plate.
Not sure if you want to specify these to have a different/duller finish from the armor... With what we've seen in the current stl and cast offerings, these parts are modeled in. I can foresee them simply being painted along with the armor by most. Personally, I like the idea of having 4 holes on each side of each plate to thread leather piping through to get the effect of a different finish but I don't think we want to be that specific.
Of course there's always the option of using a flat/satin red paint over the greeblies after final clear coat to dull them out but how many GMLs are actually going to look for that, especially if it isn't laid out in the CRL? If we're ok with them being the same gloss finish then it's moot anyway.
