The trade-off is that the color selection is far less, and I had to custom dye mine. The upside to dying it is that RIT dye has an amazing dye mixing guide on their site, and we were able to get the perfect colors.
So, if you don't mind dyeing your own fabric, I suggest twill for the jacket. It holds shape much better than Kona.
Edited to add this link to my Mako, so you can see the drape of the twill. http://www.cosplay.com/costume/433733/
Ah, thank you so much! This really helps me. This gives me a better idea of what to look for. I really appreciate the help and suggestions! Your Mako looks rad.
I actually bought two colors of suiting fabric for Mako's jacket but I'm still iffy if I want to use it because it's not that heavy but it's definitely sturdy though. I'm mainly concerned with the weight of it holding up for the collar.
Also, did you use a pattern for your pants that was appropriate for your fabric? Maybe if I changed patterns that don't use stretch material, I could go back and see what fabric I can use. I saw more non stretch fabric than anything.
