DIY Tee to Cut Out Bandeau Top Tutorial from Bleached Faded here. Really easy tutorial although Id probably sew wear she has used fabric glue. I would also again wear a tank top or something under it so it's more modest.
Lay down big puzzle pieces and spray paint over them. Wait until they dry to take the off. These would make beautiful autism awareness shirts. Autism Speaks is bad news bears for actual autistic people! Cool shirt though.
