I saw this awhile back on Style Unveiled and totally forgot to share it with everyone. I think the bride and groom were cops (thus the doughnut cake), but I think it would be perfect for a 50's wedding theme.

The rest of the wedding was more retro, so you should definitely go check it out. Seen any other great 50's ideas anyone?
