Create your own dip dyed shoes. You don't have to particularly use yellow dip-dye. I've tried this myself, and I dip-dyed my shoes blue and green instead. It really works! Make sure you have white shoes only, or else it won't work.
DIY galaxy shirt- splash/spray with bleach, tie-dye red, bleach again, paint/sponge on red/blue dye/paint and finish with white fabric paint stars flicked on. would also be a nice technique for a table cloth or throw pillows.
