I basically followed a lot of the tutorials that are readily available online and altered things where needed to match the reference that I was working from. The blue, red, and white satin's are all from the Casa collection and I also used white cotton lyrca and gold metallic spandex for other portions of the costume.
The skit is two layers - a cotton "petti" with custom lace/ribbon trim and horsehair braid in the hem and then a blue satin skirt overlaying that. The majority of the accessories were made with Worbla scraps including the odango shields, tiara, locket, and chest "armor" V. The mask is made from craft foam covered in the same white satin as the cape, but I'm not 100% happy with the shape, so I'll probably tweak it some before I wear it again. Everything attaches with snaps (so many snaps).
I used an Arda "Chibi" wig as my base wig and then followed the basic "how to make a Sailor Moon wig" tutorial. Things didn't come out quite like I wanted them to, so I plan to edit the wig a bit before I wear this costume again.
