How to Get Dolled Up for Your Fabulous 40th Birthday: A Style Guide

Turning 40 is a big deal—it’s not just another year on the calendar. It’s a milestone worth celebrating with glitz, glamour, and, of course, luxurious jewelry. Whether you’re planning an intimate dinner or an all-out birthday bash, your outfit should match the significance of the day. After all, reaching 40 means embracing life’s finer things—especially when it comes to baguette tennis bracelets and more.

Why Celebrate the Big 4-0 with Style?

Turning 40 isn't something to shy away from. According to Psychology Today’s post The Right Side of 40, written by Deborah Heiser Ph.D., we tend to get happier as we age. We become better at regulating our emotions, working through conflicts, and viewing life with more compassion.

So, what better reason to celebrate than knowing that the best is yet to come? This newfound emotional balance deserves a celebration to match—and that’s why your 40th should be nothing short of extraordinary. Let’s dive into some fabulous birthday party ideas and how to style the perfect look with our baguette tennis bracelet and more!

Five Fabulous Ways to Celebrate Your 40th

1. A Glamorous Evening at a Rooftop Bar

Imagine this: a city skyline lit up at night, the wind in your hair, and a sparkling cocktail in hand. A rooftop bar is the perfect venue to showcase not just your outfit but your jewelry too.

The Look: Think classic meets modern—a sleek black dress with a plunging neckline or chic wide-leg trousers paired with a fitted blazer. For jewelry, the Classic Diamond Tennis Bracelet is your go-to. Its timeless design and radiant baguette diamonds offer the perfect balance of sophistication and sparkle. Stack it with our Block-Chain Full Pave Diamond Thin Bracelet for an edgier, more modern vibe. Trust us—these pieces will catch the city lights and everyone’s attention.

2. A Luxe Dinner at a Michelin-Star Restaurant

What better way to mark your 40th than dining at a Michelin-star restaurant? The ambiance will be rich, the food divine, and you—dressed to impress.

The Look: Opt for something sleek but statement-making. A satin slip dress in emerald green or ruby red will perfectly complement your Bold Emerald Tennis Bracelet. This piece not only dazzles with 7.85 carats of baguette-cut emeralds, but its sleek silhouette adds a pop of color to your outfit. Pair it with the Double Short Stack Emerald Half Band to really amplify those green hues. A simple strappy heel and a bold lip are all you need to finish off this elegant birthday look.

3. A Lavish Garden Party

An afternoon garden party is ideal for a more relaxed yet equally glamorous 40th birthday celebration. Think florals, flowing dresses, and—of course—beautiful jewelry.

The Look: A pastel-colored dress with soft, flowing fabric is the perfect choice for this outdoor affair. Go for something that feels breezy yet polished. For jewelry, stack our Bold Burst Rainbow Sapphire Tennis Bracelet with the Classic Diamond 36” Inch 50/50 Tennis Necklace. The vibrant colors of the rainbow sapphire baguettes will add a playful yet sophisticated pop to your look, while the classic necklace gives you that subtle touch of timeless elegance.

4. A Private Yacht Party

If you’re going big for your 40th, why not rent a yacht? The sea, the sun, and you—decked out in diamonds. This venue calls for an outfit as bold as the occasion.

The Look: A statement-making white jumpsuit or a flowy maxi dress with oversized sunglasses will make you feel like a movie star. Add our One of a Kind Opal Doublet Shield Ring for a bold statement—its vibrant play of colors paired with white diamonds makes it a true conversation starter. Stack this with the Classic Gold Full Baguette Milli Eternity Band for a little extra shimmer.

5. An Intimate Dinner Party at Home

For those who prefer something more intimate, a dinner party at home with your closest friends and family can be just as glamorous. A cozy yet sophisticated evening, surrounded by your loved ones, is the perfect way to reflect on your fabulous 40 years.

The Look: Even at home, you can (and should) bring the sparkle. A midi wrap dress in a jewel tone will give you just the right amount of elegance. For jewelry, we recommend our baguette tennis bracelets —perfect for both casual and formal occasions, with their seamless design and effortless wearability. Add our La Fantaisie Star Diamond Signet Ring to give your look that touch of whimsy and tradition.

How to Style Tennis Bracelets Like a Pro
