I made this for the current version of ALOT for old ME1, but as I'm currently discussing with CreeperLava, Legendary Edition armour meshes were changed so the textures are not lining up correctly with ME1 meshes. This was going to be the start of an updated mod I was making to add detail to the rather plain ME1 armour sets, not sure what CreeperLava has planned to fix the problem so for now I'm just going to upload these textures as a modders resource which means you can use them as you like.
I do not own LE so this will require a small amount of work to become a usable mod, for anyone with experience of working with textures for Mass Effect this will only take a few minutes but do not install these as they are or they will not work.
The textures are just diffuse standard LE with edits, you will need to add them to the medium Male and Female Survivor textures, just add layer mask to the vanilla texture and choose transfer layer's alpha channel, remove its alpha channel then copy paste my diffuse to the vanilla one (not the layer mask) then right click the floating selection and hit anchor layer, export with mip maps and you are done. Stick them in a MEM or you can use them as they are with ALOT installer.
Do what you like with them, upload as a little mod if you like, use yourself, or include as part of another mod. If anyone would like to take this idea and do more armour sets (which is what I'm trying to do with old ME1) be aware everything is mirrored which limits the designs you can make hugely. You will see how I got around this limitation if you look at the screenshots.
