This is just a rough guide on how I made my Asuna cosplay, not a step-by-step tutorial. It's an intermediate project, and I would not suggest it if it's your first time sewing! You'd probably kill yourself from frustration. That said, if you have any questions, don't hesitate to contact me!
Top ($7) - I used white bridal fabric. It was a general top pattern that was extended a bit. This is the basic pattern. Darts (dashed blue) were taken in to better fit my body. I first cut out the pattern in gift wrap before transferring it to fabric. Then I pinned it to myself and made darts from the shoulder to the bottom of the top (dashed blue). This is important so that it's a good fit. Then I sewed red bias tape onto the straight part of the darts (therefore hiding them) and onto the edges.
Here is a picture of me taking in the darts (the left side is done, the right side is just the straight dart).
Don't forget to add the thin red ribbon and the cross shapes at the bottom, as well as the circle shapes on the collar. I cut those shapes out of red cotton fabric, added no-fray glue to the edges, then carefully sewed them onto the fabric. For the collar: I traced one of the collars on my existing dress shirts to get the pattern. I can't remember what it is off the top of my head. I also added velcro for attachment of the armbands and chest armor.
There is a 20in zipper down the middle of the back. Make sure you account for seam allowance.
For the skirt, I cut out a huge rectangle, sewed double-sided white bias tape on.

Here is my box pleat! There are a lot of tutorials on box pleats, so I won't go into detail here. It is a time-consuming process though.
Armor ($7) - I bought 3mm craft foam from Hobby Lobby. The chestplate is basically 1 big rectangle to cover the chest, and 2 smaller rectangles that wrap around my body. I first made a template out of poster board before transferring it to foam. This picture is actually my second layer of foam; I cut out slits on one side because I already had velcro on the first layer of foam, but the two sides should be identical (without slits).
I made 2 darts in the middle of the big rectangle to account for my boobs.
I used 2 layers of 3mm white craft foam. For the next part, I followed Yumi Cosplay's Asuna tips. I cut out the gray edges from a thinner craft foam and then glued it on with super glue.
This is what the finished armor looks like after using mod podge and acrylic paint, and then weathering it. I put some scrap white fabric on the back for support. The armor is attached with velcro (sewn into the foam) in the back.
I added this part separately. I glued it on with a piece of foam in the back and hot glue. For the crosses, I cut out crosses on 2mm foam, painted it, and then glued it on.
I trimmed my white rainboots, and then made craft foam slip-ons. The slip-ons are basically a trapezoid shape and a rectangle with extensions. I glued a second layer of foam on top, and then backed it with leftover fabric.
Wig ($30) - Ebay seller, Beadsweb.
Red and yellow armbands ($8) - Detailed tutorial here. I made it red on the outside and yellow on the inside. The reference picture looks like it could be yellow on the inside, but it's not clear. It could be red on the inside too xD. The pattern is basically 2 big X's connected in the middle. It's more clear in this ebay photo. I pinned and then sewed yellow bias tape on, followed by skinny yellow ribbon. It's attached with velcro to the main top.
For the arm gloves, I draped stretchy white fabric over my arm, pinned it, and then sewed it. Then I cut out a red knit fabric and hand-sewed that on, along with the lace. I put liquid stitch along the ends of the red knit fabric so it would look neat and not fray.
Stockings ($2)- I draped stretchy white fabric over my leg, pinned it, and then sewed it on the sewing machine (while stretching it). Then I pinned red bias tape on the stocking as it was on my leg, and then sewed that on. Then I trimmed off the excess white fabric of my stocking so that the bias tape would line up with it.
Then I cut out the cross shapes from some stretchy red fabric and pinned /sewed them onto the stocking.
Then I pinned my stockings onto a pair of nude stockings while I wore it. hand-sewed the top of the stocking onto a pair of nude stockings with a curved needle.
Then I used a curved needle to hand sew it down while I was wearing the stocking. This is easier than stretching it on the sewing machine, but more time consuming. I don't think this step is possible without a curved needle.
For her white skirt, I sewed a hemicircle, and I put lace on the ends. She doesn't really have lace on the skirt. I just thought it would look pretty based off of this Asuna cosplay I saw on ebay.
I got the sword commissioned by Codykoko Cosplay. (If you want to make her sword, you can follow SoynutsProps guide.) It's a sturdy sword with just the right sea-green color, and a brilliant metallic shine. However, I wanted to make some modifications.
My friend SoynutsProps sent me the leaf thing on her sword. I painted it with acrylic and varnish and then glued it to my sword with E-6000.
I used $1 nail polish from Family Dollar to make the dull blue jewel shiny.
