Hello all! Sorry for the slight necro posting, but I’m continuing progess on my Cortana suit. I’ve run out of materials fro my MK VI armor and am also currently out of money to buy more, so I’m redirecting my attention to my Cortana for the time being. My plans are to improve my wig, and build a chestpiece and padded bottom for the suit. If I can ever find more of the suits material again I will also be making matching gloves.
As pointed out by the lovely Kiotoko-Solo, who has a beautiful Cortana costume in progress, there are certain aspects of Cortana’s anatomy that are more exaggerated than on regular folks.
Materials that will be required are:
One pair granny panties (try to get them a size larger than you normally wear as you will be filling this extra space with padding. Can be obtained anywhere that sells underwear. I went with walmart because they’re wicked cheap and I don’t plan to wear them everyday. Go with either white or a nude color because you don’t want these to show through your costume.
Regular density foam- found in the foam/pillow section of most craft stores. You’ll need about a 2 foot square (this gives you a bunch of room for error) and aim for the inch thick stuff. I was lucky and got a rememant chunk for only $3. Woot!
About an 8inch square of any scrap fabric or waxed paper/parchment paper. Whatever you have lying around will work really. This is just to make an outline with.
Measuring tape
Black Sharpie
Glue of choice -I used tacky glue because it’s what I had available. Note that tacky glue is water soluble so you’ll never be able to wash these. Plan to either wear different underwear beneath these ones or invest in a different glue.
Scissors and/or exacto knife
Since every body is a different size please customize your measurements or you’re going to have an odd looking bottom.
Your goal is to have 2 tear-drop shaped pads approximately 6-8 inches tall and 4-6 inches wide depending on your natural butt size. Start bigger than you think is necessary because once you try them on in the underwear you can really see where you need to shrink and shape them. Mine started out as 8 inches tall and 6 inches wide but by trying it on and shaving down the edges it ended up being 4.5 inches wide and 6.25 inches tall.
Make a pattern that looks something like this:
Trace the pattern onto your foam. You want 2 foam teardrops. Arrange them so the flatter sides are together like so.
Now, try on the underwear and stuff the pads in. Use a friend or a mirror to get them even. Note where they are too thick and stand out from the body too much. I had to trim the top half of mine down to about a quarter of an inch thick so it didn't stand out awkwardly from my body. Now it;s all shape and shave off bits until you get the desired look. You are shaving off the side that will be glued against the panty. Taper all the edges for a nice rounded look. If you're using scissors, basically all you have to do is cut all the edges at an angle out from the center. Picture it like you're making a really short mountain.
Once you’re happy with how the foam sits and feels, bust out some pins. Pin the foam chunks in place and start to glue them. I started with the thin top of the tear shape so the glue would hold the pad in place. You are gluing the shaped side to the underwear, so the flat side with no tapering is against your own skin. Apply glue directly to the foam not to the panty unless you want to deal with one heck of a cleanup.
Repeat for the other side. Now you just have to wait and let them dry. Mine took about an hour. Try them on and make sure you’re happy with them.
My final result
I hope this helps any future Cortanas get their desired shape!
On that note, I'd also like to share my wig 2.0. Notice the new cut and added beads
I've also fixed up my technique for the makeup a bunch.
