The harsh answer is, if you feel uncomfortable with the design, don't cosplay that character. Choose a character who you'll feel more comfortable with cosplaying.
But if you are dead set to wanting to cosplay this character, you can always modify the design slightly so it will make you more comfortable when you're cosplaying. I did the same for my Oichi cosplay. Her outfit design is very short, but what I ended up doing was just making it a bit longer enough that I would be able to wear it and feel comfortable.
