Throw it back with a retro karaoke night that celebrates her latest milestone but gives a nod to her early years. 

For an at-home party, queue up a 40th birthday party playlist with some nostalgic ‘80s and ‘90s hits, have guests dress the part, and put up a photo booth for pictures. Or if you know of a local bar or club that hosts karaoke nights, go celebrate the special day with a bigger crowd. Either way, this celebration for the birthday girl is sure to hit the right note.  

2. Dinner Party

Turning 40 is the perfect reason to dress up and feel extra special. Book the newest five-star restaurant in town and feast on a drool-worthy meal with beautifully presented cocktails and perfectly ornate centerpieces. Jazz it up by picking a place with live music or a piano bar.

3. Wine Tasting

Be sure the birthday girl savors her 40th birthday — literally — by planning a wine tasting party. Book a wine tasting at a local venue or vineyard nearby your hometown. You don’t even need to be close to Napa Valley. Or, if wine isn’t really the honoree’s style, go beer tasting at a local brewery instead. 

Indulge in a variety of flavors by seeking out flights instead of glasses, and in lieu of cupcakes, purchase the guest of honor a bottle of her favorite wine (or growler of her favorite beer) to take home for dessert. 

You can also purchase elegant tablecloths to adorn tables at your own house, hire a sommelier, and ask guests to participate potluck style by each bringing a bottle of wine for tasting. Add some fancy cheeses and dark chocolates as a fun way to sweeten up the gathering.

4. Game Night

Go for the win with a game night theme party that gets everyone excited and involved. This is an especially fun way to celebrate if the birthday gal’s a big board game or card game enthusiast and prefers a more casual or intimate gathering. 

Be sure to incorporate some of her favorite games and throw in a few that are specific to her turning 40, like trivia from the year she was born and the decades she’s lived through. Add some pizzazz to the evening by purchasing game-themed birthday decorations and party favors. Maybe even buy her some new board games as birthday gifts.

5. Spa Day

There’s nothing like a spa day to recharge, rejuvenate, and fully relax. Pamper the guest of honor and her closest friends with a group spa package, or book mani/pedis and individual massages. Consider going the extra mile with personalized robes for the diva experience.

You can also host your own DIY spa day with fun activities at home. Grab some of the birthday girl’s favorite nail polish colors and facial supplies, tee up a soothing playlist, and burn some incense for a soothing and tranquil afternoon.

6. Brunch

Gather the girls and get toasty with a late morning brunch. If you don’t already have a go-to brunch place, hunt around for one that offers a unique setting, is exquisitely decorated, or just has the best reviews and menu. Pop some bubbly and celebrate over mimosas, or order up a round of Bloody Mary’s if that’s her style.

If a more intimate setting is preferred, or you don’t want to worry about being too rambunctious in a public establishment, set up a brunch in your backyard with fresh flowers as centerpieces and a garden landscape as your backdrop. 

7. Getaway

A major milestone like turning 40 can be a great excuse to book a trip, near or far. Has the honoree been dreaming of a beach vacation? Wanting to conquer her next big hike? Or is there a concert or Broadway performance she’s been talking about wanting to see? Make it their most epic birthday yet by booking a trip. 

If the bday girl is laid back and up for anything, surprise her by booking all of the details and packing her bag. She’ll never expect a thing.

8. Shopping Trip

Oh Invitation

If the soon-to-be 40-year-old in your life isn’t big into the spotlight and birthday festivities, go to the mall or a favorite clothing store for a low-key shopping trip. It’s likely the birthday gal usually focuses on other people and doesn’t have much time for herself, so give her a shopping extravaganza that caters to her own wants and needs for the afternoon.

9. Casino 

Destiny Invitation

Feeling lucky? Wager on a good time by planning a 40th birthday celebration at a casino in your area. (Though if Las Vegas is in the budget, it’s always a nice option too!) Pool some money with other loved ones and give the guest of honor “free” money to gamble with. Just remember — no strings attached! If they hit the jackpot, they keep the winnings.

10. Movie Marathon

Sometimes low-key nights are the most memorable. If there’s a series she’s been dying to binge or a new chick flick that recently came out, staying in and vegging out for the night could be the perfect way to celebrate the milestone birthday

Have her favorite movie treats and popcorn on hand and a scrumptious birthday cake, along with a variety of comfy blankets and pillows. Enjoy a comfy evening on the couch or in the backyard under the stars with a projection screen.
