Miku Vocal Module Vest

Welcome to the next step after crafting your skirt and purchasing your wig. It’s time to start making our vocal module vest, woo! When going through this process, I cannot stress it enough how important it is to make a muslin vest first. This way you can really figure out what went right or wrong during the process and adjust for any issues you may potentially come across. I have come to realize over time that this is such an important piece of the process.

Vest Fabric Choice

You’ll want to figure out what kind of fabric you want to make your vest out of. If it’s during summer, you can choose a fabric that has a lighter weight. During winter, you could still choose the lightweight fabric, but you might be chilly depending on your location. I typically choose my fabrics based on feel, weight and comfort potential. Avoid picking things you won’t be comfortable wearing for long periods at a time.

Vocal Module Top Color Choice

You’ll want to decide what shade of yellow you want your vest to be. For my own vest, I chose a bright, lemon yellow with a cotton/spandex blend for the front bodice and a bright yellow, cotton broadcloth fabric for the back bodice. I wanted something for warmer temperatures so I chose lighter fabrics. 

Materials Needed

  • Fabric
  • Pattern tracing paper
  • Tailor’s chalk
  • Sewing machine
  • Thread
  • Pins
  • Needles
  • Scissors

Step 1: Find and Trace Bodice Pattern

If you haven’t already, you’ll want to find a pattern for your top or create your own, which is easier said than done. For this project, though, a basic, sleeveless turtle neck pattern would do. You could also do a smiliar, sleeveless waistcoat pattern, but you would have to add the collar in yourself. You can add any alterations as you design the pattern. My own pattern was a basic block of a front and back bodice where I added extra length to the top.

Step 2: Cut the Vest Pieces

Now that you have traced your pattern, you’ll want to lay it out on muslin fabric first and trace the pattern onto the muslin with tailor’s chalk. Make sure you follow the grain with this so that your pieces will be uniform. After you’ve traced the pieces using tailor’s chalk, you’ll want to cut them out, keeping in mind to cut out room for your seam allowance as well. Some patterns include the seam allowance, but many don’t, so make sure to double check and accommodate for this before cutting out your fabric. You don’t want to have to cut twice and waste fabric.

Step 3: Put Vocal Module Vest Together

If you have instructions, you’ll want to go through and follow those. For those that are just doing it on the fly without instructions, though, you’ll follow these steps.

  1. With the right sides together, match the shoulders together and sew the front and back bodices together. Leave about 1/2in from the curved portion of the shoulder.
  2. After the shoulders, sew the sides, making sure not to sew the armholes. Leave about 1/2in before the edge of the fabric.
  3. With the extra 1/2in to spare, you’ll want to fold your armholes over and make a small hem. That way your edges are finished on the armholes. You can choose to do a zigzag or other finishing stitch, or you could leave the straight stitch alone. Remember that fabric frays over time though so be careful if you just leave the straight stitch.
  4. Depending on the pattern you’ve chosen, you may have to attach a zipper. If you do, go ahead and do that now.
  5. Finally, finish off all the raw edges in whatever way you choose, and you’re done!
