Princess Boo

„Notice me Luigi  (´•ω•`)♡“

“Don’t look at me!”



Princess Boo, also known as Booette or Boosette, refers to a genderbend Super Crown fan art of the Nintendo character King Boo as a princess. Alongside Bowsette, the character saw a surge of fan art amidst a wave of Nintendo characters being drawn as women after the introduction of the Super Crown mechanic into Nintendo lore.

When the whole internet fell for Bowsette I wasn’t very interested in this figure but as soon as I saw the Boosette version my inner goth fell in love with her. I instantly knew that I had to cosplay her and which event would be better than Halloween? I also wanted to try something new so I decided to sew a princess dress in white.

About the Project


December 3rd 2018

Purchased Items

The wig, the ears, the gloves and the stockings are purchased.

Selfmade Items

I sewed the dress and the collar. The rhinestones and the crown are selfmade aswell.

Nagini as Boosette

For this dress I used a pattern from Burda for the first time in my life. I’m not a professional sewer and the pattern and instructions were really complicated for me. It took me a lot of time and patience because I often had to reopen what I sewed but in the end I never gave up and am pretty happy with the result.


This cosplay costed me around 100 CHF.


I used polyester fabric and lace for the dress. In the back is a zipper and in order that the sleeves stay in place I attached some elastic band. For the crown I used Worbla Finest Art and Worbla Crystal Art for the rhinestones.

Making Of

The dress

I’ve seen many different versions of Boosette but I imagine her as the ghost princess and this means for me that she wears a princess dress.

I searched for a pattern I liked and found a beautiful dress pattern from Burda. I never worked with a pattern from them until then and I was pretty overhelmed from the manual. I took my time so that I can be sure that I’m doing it right and after I bought the fabric needed I started with cutting out the pieces. Piece after piece I sewed together and when the biggest part was done, I had to realize that it was too big for me. This discouraged me for a while but I didn’t want to give up and started a new try. The second attempt was succesfull and even when I didn’t made it 100% as described in the manual, I’m very happy with the outcome and it’s wearable!

The crown

I struggled with start doing the crown since I wasn’t sure with which materials I should work.

I decided to buy a styrofoam ball for the middle part and looked for crown patterns in the internet. I tried different shapes out until I was content with the result and traced it to foam. After that, I covered the foam and the ball in Worbla and put it together. Then I added the details. When I was satisfied with the result I primed the crown and painted it. I attached the crown to a headband so I could wear it.
