My husband, being a long-time avid Nintendo fan, noticed that our 20 month-old son could look a lot like Young Link from The Legend of Zelda. A Halloween costume project was born! I have to say, this didn’t take nearly as long to piece together as I had expected. After putting together the costume, we went out for a fun little photo session in a nearby park. My husband then added some Photoshop wizardry to bring some of the other fantasy bits to life.
I began by looking online to find a tutorial, and found a great one which doesn’t use a traditional sewing pattern here: http://meowaboutcosplay.com/guides_tutorials/link.html#tunic The following is the section of the tutorial that I used to make an easy and adorable tunic. She made a sample tunic before she made the actual one out of nicer fabric. I decided to just dive right in. Some tips about using this tutorial: make sure to cut the neck hole big enough to fit “Link’s” head through if you’re using non-stretching fabric (my green fabric had no stretch). Also, I made mine too long the first time and had to cut some off once I tried it on my son. Thankfully, my mom has a serger sewing machine, so she finished off the edges for me. This way, I didn’t have to put a hem in the fabric and that saved me a lot of time.
“Green Tunic I got about a yard and a half of cheap fabric to make a sample with. I folded the fabric in half and laid an oversized T-shirt across the fabric so only half of it was on the fold. I used a permanent marker to trace where the neck, shoulders, and bottom of the shirt were on the fabric. The sleeves will be a separate piece, so I didn't trace those.
After tracing and cutting out the front and back of the shirt (the front has a "V" shape cut into the front), I sewed the sides and shoulders together. I made a few adjustments to the T-shirt - I made it longer, and flared the sides out slightly below the waist. At this point, the garment looks like a long, shapeless vest. Adding the belt helps give the tunic most of its shape. If you want to make a really fancy Link tunic, you can make the basic tunic two separate pieces - the shirt part for the top, and a gathered "skirt" for the base. The skirt part should be a very wide strip of fabric (at least twice the width of your waist), which you'll gather and sew to the top. This will give you a more flared-out base, but you'd run the risk of making it look too much like a dress. The simplest way to make this is to do a one-piece tunic. The collar was a little more difficult to make than the basic tunic. Using the "V" cutout in the front of the shirt, I drew the collar shape on another piece of scrap fabric and cut it out (1). Then I cut out another one, mirror flipped (2). Finally, I put these next to the "V" shape and cut another piece of fabric for the back of the collar that was the remaining space between the two collar front pieces (3). I sewed these three pieces together to make one big collar piece, then I sewed that to the "V" of the main shirt.”
