This is more like "Is this a good fabric to use?" question but I kinda felt like it belongs here!
My mom and I went out to the fabric store and I kinda got sticker shock ($20 per yard of cotton, where I used to live, cotton was like $4 per yard and I only had about $60 to spend on the fabric) So we went to the back rack were they had the sale. My mom picked up a black fabric that turned out to be polyester and it's really nice.
Is that fine to use for the jacket of Ciel's outfit, or should I spend another $60 on the cotton? I'm still pretty new at sewing my own cosplays .________.
