Evening, /cgl/!

Can we have a intricate design or difficult cosplay thread with tutorials on how to do more advanced costumes? My picture is related; a few years ago, I found the openings to Makai Tenshi Djibril and fell in love with the design for the outfits. Since, it's been my dream cosplay. However, I have absolutely no idea where to even begin to think about starting; I was hoping maybe a tutorial on making plugsuits would be helpful?

Anyway, thanks in advance for any advice or tips!
