Vest 
To dream that you are wearing a vest is an indication of your good and charitable nature when it comes to those around you.
Bulletproof Vest
Wearing a bulletproof vest in a dream is a sign of being vulnerable in your waking life. You feel like people are 'taking shots at you' and you are taking action accordingly in your dream. Though the threat of bullets may be figurative, you are being emotionally wounded by others in your waking life and your subconscious is trying to tell you to take protective action.
Suit
To dream that you are wearing a suit suggests that you hope that others will appreciate your efforts and talents. It would not be beneficial if all of these attributes were ignored.
Armor
To dream that you are wearing armor represents the methods you utilize to protect your feelings and emotions from harm. You are afraid of letting others get too close to you, so you erect barriers to guard your inner self.
Life Jacket
To dream that you are wearing a life jacket represents self-preservation. You crave support from those around you.
To dream that you are not wearing a life jacket indicates that you want to deal with your problems without getting too emotional, despite potential pain and anxiety.
