Eternal Sailor Senshi Cosplay Guide


By and far, Sailor Scouts are some of the most cosplayed characters at conventions. Being an old favorite, it means there are tons of tutorials and accessories available online which makes it easy for anyone to make their own costume. When making my own Eternal Sailor outfit with my group, we used a lot of things available online such as patterns and accessories, so I wanted to share these resources with you!

Leotard pattern modifications

Crystal Lake Skating Outfit

This leotard pattern is used by many Sailor Moon cosplayers. It’s easy to sew and doesn’t need many modifications. I recommend lengthening the top piece of the leotard a bit so the seam that normally would be at your waist ends up being lower and therefore hidden by the skirt. I also recommend making the neck hole smaller so that you can cut it the same size as your sailor collar later. Otherwise the hole might be too large.


Sailor Neptune and Uranus bows and collars

Interface the crap out of your back bow so it stays upright!

I strongly recommend doing a mockup to adjust the collar to the width of your shoulders before cutting into your nice fabric.

Bubble sleeves

I made some optional changes to this pattern when I used it. My upper arms are a bit large so I was afraid that if I used the pattern as is, the fabric wouldn’t be gathered enough and therefore the sleeves wouldn’t have enough volume. I slashed the pattern in 4 pieces and placed them a little bit apart at the top edge and even more spaced at the bottom of the sleeve. This is not necessary for everyone, especially if you have small arms. Measure your arm where the sleeve will end and compare this number to the length of the pattern. I think the pattern being 1.5 x your arm circumference is good enough.


Eternal Sailor skirt progress

For the skirt we made a double circle skirt (2 circles sewn together) that is 3x the measurement of your waist. For example, if your waist measurement is 30 inches, you need to multiply that by 3 and then divide by 2 to figure out the waist circumference of each of your circles.

(30″ x 3) / 2 = 45″

Take your own circumference measurement and use this calculator to figure out the diameter of your waist opening. Remember that you will need to make 2 circles with the same waist measurement!

If you’re unsure how to pattern a circle skirt, you can check this helpful guide by the Snugbug Mercantile.

After you sew both circles together you’ll be stuck with a giant skirt that probably fits 3 of you. That’s ok because you’ll use all that extra fabric to make your 12 box pleats!



Eternal Sailor Scout Tiara from Catzia’s Collectibles

These are very good quality and attach to your head with an elastic. The star on the front of the tiara is glued with hot glue and in my case the glue was showing around the star. I used rubbing alcohol to remove the hot glue and glued it neatly back on with some contact glue.

Small gold stars

Small gold star

You need 4 of these for an Eternal costume: 1 for the choker, 2 for the boots and 1 for the skirt’s waistband. Catzia’s Collectibles sells the gold stars as add-ons for their chokers, but they let us order these separately for $1.95 each. The color is an ugly yellowish gold so I spray painted mine metallic gold.

Alternatively, you can probably find similar stars on eBay for cheaper.

Star brooch

Initially I bought the brooch from Catzia but I decided to order another one from ShoujoGems because I though their brooch looked less cartoony. Sadly, she no longer makes resin items, but you can get a similar star brooch from UniqueCosplayProps on Etsy.


Our group used the Kiki 350 boots by Funtasma in White Stretch PU (non shiny material). Many stores carry that brand so you can shop around for the best price. I have large calves so these were good for me since they were stretchy enough to fit me. Other girls with smaller calves had to take in the boots a little bit. You just need to cut a V shape at the top.

Horsehair braid

Horsehair braid is what makes the magic happen in magical girl skirts! We sewed 5/8 inch braid on the hem of the 2 skirt layers.

Here’s a tutorial by Jessie Pridemore showing how to put in horsehair braid.
