The outfit look real good after you release the light version, but i think you can improve more, i will put my suggestion here so the comment wont get flooded

Where the armor add-on right now are perfect, but the armor model still look too thick (it feel very heavy) & texture look very dirty, it feel like rusty metal or stone more than "clean/light/well-made" steel

- Arms armor doesnt cover the whole lower arms (from elbow to wrist), "extent" it more, about 1.3 to 1.5 time longer should be enough
- Need legs armor (from knee to foot), just like the arms armor above, cover the whole lower legs, not like the 18/22 image, only a small armor & the sock cover part of it make it look lame
- Remove "elbow armor" from "medium dress" & white "short dress", it may look clunky when the lower arms armor are extent enough
- Remove "knee armor" from the "medium dress", it ruined the "dress & apron", NEVER touch "dress & apron", it the soul reason why maid outfit look like maid

You can use model & texture from vanilla item, here is some good material, they look nice, light & clean, perfect for how maid armor should look like:
+ "Armoured rags & Conscript leather armor" for lower arms armor
+ "Plated longboots" for lower legs armor

If it hard to imagine, just look at Noel, like i said, the golden standard: "light but well armor", "clean and elegant", distinguish as a maid, and is how an armored maid should look like
