I've literally had this top for like a year and have only worn it once because it was SO boring. I finally decided to spruce it up a bit, add a little neon and now I'm in love.
I used acrylic paint I purchased a while ago at Michael's for like 50 cents. HOWEVER, I would recommend using fabric paint so that your clothes don't feel all hard & crunchy once it dries. So grab your supplies & 30 mins later you'll have a far more exciting shirt with little effort. Happy DIY'ing people!
