Bring some or bring them all...
Handwritten vows or letters (I recommend vow books or postcards from your location)
Wedding Invites and save the date
Sentamental items/heirlooms (grandmas veil, picture of loved one who passed, family heirlooms, etc.)
Again- Anything you want in these images is what you should have ready! What do you want captured that I wouldn't know about but is very special? If you aren't sure if it should be included just reach out and ask. And nothing is required, if you don't want pictures with your perfume, no biggie!
