Chibiusa's Retro Space Senshi design is the work of fan artist Hyamei, who created a mashup between the Sailor Senshi and 1960s-style science fiction/space fantasy design, similar to that used in the series The Jetsons. All 10 senshi are depicted in the artwork, and the designs themselves are based off of the characters' Super Senshi transformations.
I rarely have the desire to make a costume based on fanart but these were too cute to resist and I quickly got a group together. I knew I wanted to integrate LEDs into the design, and came up with a way to thread the lights into the chest and butt bows while using translucent glitter casa as fabric. I imagined a way to layer the fabric in my head to hide the wires and still allow us to use interfacing, and to my surprise, it actually worked in reality the first time I tried it! The skirts are layered half-circle skirts which zip up the side and are puffed out with a petticoat and a large plastic zip ties sewn into the bottom hem. The skit goes over a store-bought leotard with sleeves attached using a stretch stitch. The triangle-shaped collar was hand-patterned and made as a "pocket" of fabric with interfacing, while the heart gems are cast in resin and glued on.
The most challenging part of Chibiusa's design is the space helmet; I decided to get a kid's toy astronaut helmet which Sketch cut in half, cut holes for my odangos, and reshaped the visor to the curved edge found in the artwork. The circle pieces where found at Michael's, which we painted with the crescent moon and screwed them onto the helmet. A wooden dowel with a LED and glass ball finished off the top. We accented everything with glowsticks and store-bought bubble guns from the toy store; we had a blast blowing bubbles around the lobby at Dragon*Con. I'm pretty happy with how this came out, though I want to do some more minor detailing before I wear it again.
