Before you can make any costume, you need to get the measurements for whoever you're making this outfit for.

Specifically, make sure to get the circumference of: your arm, forearm, bicep, hip, waist, bust, & head. Then, make sure to get the length of: your arm, leg, stomach, torso, shoulder width, back, torso to arm.

For sewing it is quite easy.

For the arm warmers get a pair of pants that have elastic on both ends. Cut them down the middle and make shorts out of the pants. Then sew the raw edge up.

For the tie, cut the sock at the heel. Then sew the raw edge down and put a string through the sock and sew the sock to have a pointed edge.

For the shirt thrift a white shirt that is collared and fits you.

For the skirt this is the most complicated part. From the long sleeve shirt, you will cut a rectangle that is far too long. Then you sew the edges of it to make a loop. Then you put an elastic band in the top and hem the raw edge.

And now you have Miku's clothes!

First, draw out your design on a piece of cardboard. Then, get your hanger wire and mold a general shape that reflects the design. Use your hands or pliers to manipulate wire as some bending could be difficult. Both ends should end at the middle of the wings. Form a square like shape and twist the ends.

To add on tulle/fabric over the wings, cut out shape with 12 mm (~0.5 inch) allowance then hold fabric over and hot glue in place.

To connect them to the servo arm, grab a X-acto Knife and twist around servo arm holes. Be careful as they could break. Thread them through the arm as shown in picture 4 and hot glue them in place.

This electrical diagram showcases the motors, and possible fairy lights ( decided not to add later on) that hook up to the raspberry pi pico.

First, hook up the Integrated Power Module, aligning the positive and negative rails to the pins

Here’s how to connect the servos to the breadboard

Servo 1:

Positive pole -> Positive Rail of Breadboard

Negative Pole -> Negative Rail of Breadboard

Signal -> GP0

Servo 2:

Positive pole -> Positive Rail of Breadboard

Negative Pole -> Negative Rail of Breadboard

Signal -> GP1

Copy the following code and open up Thonny (Python Program) or other IDE:

In order to have the code run on the Raspberry Pi Pico, connect your Pico to your computer and then on Thonny (or other IDE) move code in the “main.py” file in the pi pico memory.

In essence, this is used to make the servo motors move to flap the wings around. This allows for the wings to move in perfectly reflective angles.

Of course, if your code doesn't work, make sure your wiring is correct..

Export Case Model and print it out (Project used a Bambu printer). Place Velcro on the body of the shoulder strap and velcro on the back of the box.

First, put Servo 1 through the left servo hole and place Servo 2 through the other hole. Next, place the breadboard inside, making sure the Integrated Power Module button is aligned with the hole. Last, plug in the battery and place it on its side in the middle of the breadboard.

The slant is there to make wing movement possible. If satisfied with wing movement, use duct tape to hide the microcontrollers

In order to close the box press the two sides together

One of the most important things in this step is that you need to ensure the wings fit through the servo motors.

One of the most prominent features of Sakura Miku's outfit are the cherry headpieces, so of course we're adding these too.

Of course, before we do anything, it's best to paint the ornaments red so the light is reflected and the red shines through more. Wait for them to dry and then, add the battery-powered LED lights on the inside. To conserve power, only turn them on when you're actively wearing the costume.

Take a string of vine and tie a leaf around the ornament hole. Cut off that leaf and make a knot. Do the same with the other ornament. Cut your desired stem length and cut remaining leaves. Use a bobby pin to pin it onto the hair

Dying (Optional)

Clip sections of twintails to desired ombre pattern. Bring pot a water to an almost boil (for bucket, transfer this hot water to bucket). Add dish soap and rit dye (This project used half a 4oz of cherry red dye + 2oz of petal pink). Dip a small tuft of wig hair to make sure you have your desired color.

Then, use tongs to swirl around the main part of the wig in the pot. Wash wig under cold water until water runs clear (Note: Dye will initially appear darker before washing).

For twintails, start dipping one into the dye mixture. The more saturated you'd like the hair to be, the more time it needs in the dye mixture. Wash tail under cold water until water runs clear (Note: Dye will initially appear darker before washing). Repeat with the other tail.

Dry wig with a towel you don't mind getting stained by wrapping and lightly stamping it.

Detangling

To start with the detangling, begin by taking a small tuff of main hair and by brushing it in a reverse motion. Teasing gives the appearance of a higher volume in the hair, and it also helps with exaggerating any style.

Now that you have your fluffball, spray it down with a fabric softner & water mixture. Once sprayed, use a hair dryer + comb (or flat iron) to straighten it. Section off detangled hair and tangled hair to reduce confusion. Repeat with twintails.

Using the flower accessories described in the previous step, now's the time to put them into action!

Put on clothes first, then wig, and lastly the wings. There you have it! Have fun with your costume :D
