Tack Bra or Punishment Bra
Items you need:
- Leather or Duct Tape (Optional)
Insert bra full of thumb tacks (for mild torture) or upholstery tacks. Typically 50 to 75 tacks on each cup of bra
You can leave the nipple area if they are too sensitive. Feel free to customize and change number of tacks depending on size of your breast.
It should appear like this from outside   and inside  
Cut 4 bra cup sized circles from leather. Push tacks through one piece of leather. Once you have them through, use glue/tape other piece of leather over the backs of the tacks so they cannot be pushed back. This will form nice padding and looks like this
