Aside from where you can see it peak up under the the top of the bringandine or along the top of his vambraces, this is the only picture I can find of Caspian's Battle Armour Under Tunic. The picture comes from The official illustrated movie companion, and has many other great pictures for reference.
For my rendition on this undertunic, I utilized Butterick Pattern B4828 and Simplicity 5574.


If you look at Caspian's tunic in the picture, it was not a solid color throughout the piece. It has a wedge cut out for the next and the sleeves are a varied color as well. So, I had to modify and conjoin these two patterns in order to get my desired look. In the pictures above you can see the wedges darn onto the pattern.


I also had to add in some seam allowance around my modifications. Also since I am using a vest pattern, I need to add length to the bottom of the chest and back pieces. Note... I did not add enough width... As a vest piece this was designed to fit closely according to the pattern, but for a shirt this is not as good... so unlike me, also add some more width to the lower portions of the front and back pieces.


Above are the pieces laid out pinned and then cut out.


Now we come to more creative work on my part... The modified front and back section. It is important to remember that when working with material, to iron/press it so you get the true dimensions you want. Pressing your interfacing to your material also makes it easier to work with so it will not slide as much. The strips above are what will make up my three sets of ties for the front of the tunic.


Here is the front piece pinned together before sewing the seams, and then the two halves complete and ready for assembly into the larger sections.

Here is the middle portion attached to the front along with the back pieces. I think it turned out very well, especially since I am just making this up largely as I go. If you notice the black threads on the shoulder seams, that is serging. I recommend a surger for anyone who makes pieces meant to last. It keeps your edges from fraying and overall makes a much nicer piece.


Here are the final pieces. As I said above the sides are a little snug around the lower waist but look great in the upper torso when on. The cuffs since I did not follow the pattern closely are a little to big, but nothing that cannot be gone back behind and either modified or lived with.
