Spotlight- The 1950's Wedding.
It is an amazing blog that features pretty much anything you can think of when it comes to retro weddings. Though the blog is heavily based in 1950's retro. It does have ideas with 1940's and 1960's themes. What I like most though, is the ideas for cute unconventional receptions. For instance, it has a post about a Sweets Buffet It also has a lot of what you would expect; dress, makeup and hair ideas.
Check it out and see if you get inspired.
