If the physics is to be believed then it should be roughly the same as being punched in the arm by a strong guy. So long as you aren't suffering from osteoporosis you should be able to take the hit. The trick with bulletproof materials is to spread the energy out, the fabric would need to be like a super oobleck where it becomes completely rigid when hit by a bullet and then return to being flexible afterward. If it is bulletproof but still acts like fabric then the bullet will just pull it along as it pierces through your body.
