Dad Passed Away

When I was 12 my dad passed away very unexpected. I'm now older with a boyfriend I've been with for a while. We have gotten so close that I'm expecting marriage/engagement not far from now. It kills me to think about how he's not going to be there to see his baby girl get married. How he won't be able to walk me down the isle. I was thinking about getting an anklet with a photo of him on it and wearing it on my wedding day. So he can "walk me down the isle" is that stupid?.. I want some advise. This is a sensitive subject for me so please be kind.
