I've been dead set on the idea of having a Mad Men party for a while now. I wanted to invite people to get dressed up, and I wanted to make a slew of kitschy, retro food. I knew that the looooooong-anticipate season 5 premiere was a thing worth celebrating, so I invited friends to come over Saturday night ("Premiere Eve") to revisit the season 4 finale in preparation.
I did have fun planning the menu, and I got more use out of the vintage mold I use for cranberry sauce. I started cooking early in the day with an apron thrown over my slip; I felt very '60s housewife-y. There was punch and a small drink-making station, and everyone dressed up. I hung up vintage ads and decorated the table with a typewriter and polaroid camera from the period. I had a lot of fun planning, and I think we all had a great time celebrating.
If you feel inspired, and want to have your own Mad Men party, might I suggest the season finale as a good time. Though, it's really always a good time to throw on a vintage dress and start wrapping chicken livers in bacon.
