    1. Hi Nelo,

      Have you thought about doing a mid-century modern birthday theme? It’s very similar to a retro vibe.

      If you’re looking for something more elegant you can do an old Hollywood glam theme. You can use teal in accent decor. I hope the party theme ideas help you.

  2. My daughter in law turns 40 on the 29 of august Anniversary of hurricane Katrina here and now Ida Hard to come up with ideas It’s so hot to decorate a park or place at the beach Was thinking maybe even just luncheon at 4 Star fancy place in New Orleans include her mom Then do fun over the hill stuff at her house when we get back .. is over the hill tacky now ?

    1. Hi Kathy,

      The “over-the-hill” party theme is not necessarily tacky, but I’ve since this theme used mainly for people who love gags. It also depends on her personality too! Does she like novelty parties?

      If she’s not a woman who’s into novelty parties, put a contemporary twist on the theme.

      To put your own spin on this theme by doing a “39ish birthday celebration” or “cheers to 40 years party theme”. For the cheers to 40 years party theme, you can use champagne-themed decor instead of beer mugs. This way, you’ll still be able to pull off the party theme concept without it feeling dated or in poor taste. I hope these suggestions are helpful to you!

Not all family get along with each other but I get a long with all. Any ideas would be greatly appreciated!

    1. Hi Carol,

      Thank you so much for the blog love! I would suggest enforcing a unique dress code for your birthday celebration. Your guests can dress in a specific color or wear an accessory ex. sunglasses. This is a great way to keep costs down. Another suggestion would be to have a Karkoe night and a playlist with classics and contemporary music. Hope these ideas help!
