Hey everyone~
So since I'm having a dance performance and I need to make a "scary looking costume" I thought "why not make a kraehe outfit?! Then I can use it twice :)"
So, for my next anime convention I've decided to cosplay kraehe!
I've never made any cosplay costumes, so this is sure going to be a challenge for me.
I would be very thankful if anyone could share their suggestions and their experiences with cosplay.
As for the costume itself I'm a little confused on how I'm going to make the tutu skirt, and how I'm going to connect that to a black shirt/leotard. Also, her top is too revealing for me, so I was thinking of using a black tanktop. Would that be alright? Or would that be too plain? Also, what would I use to glue the feathers to the underskirt?
Anyway, ANY suggestions about this cosplay would be so thankful! (maybe someone even has a tutorial *cough* that would be a miracle lol)

( Here are some sketches I made for my plan!: )
