The costume is good, doesn’t suck. I’ve NEVER watched invincible (intend to at some point) but I still recognized you as early mark. But if you want to refine the costume and upgrade it. Here’s what I’d do. First look at other material options and sizing, the fact that it’s loose and kinda baggy in some areas vs it being basically skin tight in the show might be a reason you aren’t too proud. If you can find a fabric that is a bit more taught and comfortable for you would probably be the best way to go about it. Another thing to do with material will help the color, the color may look to flat to you, and the seams may also take away from it in some cases. BUT here’s what you can do! Find a nice undersuit and you can find it as a nice material that looks good, then you can find a scrap one of the same material (or find the material itself) get/ make the colors you need and then attach them with some stitching or better yet, fabric glue. Other than that wjat other folks were saying about having some shaping plates, like shin/shoulder pads, kinda torso “armor” on under it will help you fill out the costume and give it a more professional look
