Yep, everything seemed small on Jango. The pic with both of them kinda shows the height difference between him and Boba. And yeah the shin armor looked small up close in person as well, and I also noticed it has a sort of intentional flare that starts at the middle and goes to the top of the side portion before it straightens out that's noticable on the side in that pic (the high megapixel pic I have is better and I can send it to your email-just let me know) and it seemed to not be attched at the bottom with a second elastic band because the bottow of the shin armor seemed to protrude a little as if there were only a single band along the top.
Oh, one more thing I noticed (mostly because I'm in the process of preping to sew a new jumpsuit) is that the short sleeve of the jumpsuit only has one hem line. One of the pics shows this but of course the original sized pic I have shows it better.
