18 looks + tips! What to wear to a bachelorette party in the 30s & 40s?🙂‍↕️👇

Wondering what to wear to a bachelorette party in your 30s and 40s? You’ve come to the right place! 

For a bachelorette party in your 30s & 40s, consider a cocktail dress, failproof midi dress, or a chic two-piece set for nights out. Of course, you just can’t go wrong with a cute blouse with jeans or a jumpsuit for other activities. 

When we’re young, a bachelorette night is a crazy mix of wildness and alcohol.

From enjoying male strippers to all kinds of wild shots, you are ready to dig out your statement hot bodycon dress to rock the whole night.

But when we enter our 30s & 40s, admit it, things have changed.

We do want to dress for our age and appear to be sexy yet classy at the same time.

More often than not, you just secretly hope for a spa girls’ night instead of a crazy drinking party that makes you feel awful for the rest of the week.

To make sure you fully enjoy your time, I’ve gathered 18 bachelorette outfit ideas from dressy to casual for ladies in their 30s and 40s.

I’m sure you will love it! Enjoy ladies!

1. Wear a backless dress for a bachelorette party

Regardless of your age, there’s one thing about a bachelorette party that’s remained unchanged: Dress to feel the BEST.

If you already feel so over about showing off the legs and cleavage, let’s not forget showing your back is a perfect alternative here!

There’s something special about the backless dress, it’s effortlessly feminine and sexy without trying too hard.

Whether you’re a bride-to-be or guest, you just can’t go wrong!

❤️Girl’s fashion hack #1:

Use nail polish clear coat on fraying thread ends to stop further unraveling until you can properly repair the item!

2. What to wear to a bachelorette party in the 30s & 40s? Jumpsuit

If you want to dress up for the bachelorette party with minimal effort, throw on a jumpsuit and you’re good to go!

Featuring the high waist and flare pants design, they are 100% tummy-friendly without sacrificing your style.

Together with a sleek clutch and nude pumps, you’ll never miss anything from your look.

For the brides, this white bandeau feather jumpsuit from Club L London is my best pick for you! Fabulous but looking high class.

❤️Girl’s fashion hack #2:

Prevent button-down shirts from gapping between buttons by using double-sided fashion tape <3

3. Sparkly bachelorette outfits for bridesmaids

A bachelorette party is all about celebrating the bride’s last responsibilities-free days with her bridesmaids and a festive all-over sequin dress is just perfect for the vibes.

Go for a halter neck maxi glitter dress and feel like a queen for this special day!

You deserve that.

❤️Girl’s fashion hack #3:

Rub clear deodorant on the inside hem of pants/skirts to prevent thigh chafing. ❤️

4.Silk/ satin dress to a bachelorette party

While a sundress is more for daytime, if we are talking about a five star hotel or fancy restaurant bachelorette night, I’ll always go for a simple silk dress.

It just looks womanly and high-class in the simplest way. If you are on a budget, let’s not forget satin dress is equally flattering!

Of course, an oversized blazer is always welcomed for a dash of boss lady vibes.

❤️Girl’s fashion hack #4:

Use rolled-up magazine pages to maintain boot shape when storing – truly work wonders imo lol

5. Add an extra pop of fun to tassel dress

For the ladies in their 30s and 40s, I get it, you want sometimes fun but not too over the top for the bachelorette party.

If you are going to dance, I’m sure you’ll have a blast with this tassel dress.

It just brings a touch of fun and makes you dance like nobody is watching.

❤️Girl’s fashion hack #5:

Stretch tight shoes by wearing them with thick socks and blowing them with a hairdryer!

6. What to wear to a bachelorette party plus size?

For the girls who are looking for something tummy flattering, a peplum dress is such a godsend.

Featuring the extra flared fabric gathered around the waist, it just covers the tummy totally and fakes an hourglass figure for you.

Below are my two high-quality picks from Amazon, enjoy!

Off-shoulder peplum pencil dress? This gorgeous piece just can’t be more slimming.

Want to spice up the look, this cold shoulder dress is perfect. It comes with many shades too, check it out!

❤️Girl’s fashion hack #6:

Quick fix – Brighten yellowed white clothing by soaking in a solution of lemon juice and hot water!

7. Bachelorette party dress code ideas: blazer dress

Whether you are the bride or guest, a structured blazer dress is for you.

For a posh girl look, opt for the double-breasted gold button ones to give out the vibes.

Trust me, it looks super instagrammable when you girls coordinate the “Don’t mess with me” blazer look together.

❤️Girl’s fashion hack #7:

Whenever I feel bloated, I’ll always use a rubber band to loop through a button hole and around the button for a temporary fix to pants that are too tight!

8. What to wear to a bachelorette party in winter?

When you are in your 30s and 40s, you just no longer stand the low-quality cotton dress anymore.

To stay glam at the winter bachelorette party, a velvet dress just look incredibly sophisticated and lush.

With the buttery soft fabric, It just hugs your curves in the comfiest way.

Together with a sleek low bun and a dainty long necklace, you just prove to the world that dressing tastefully for a bachelorette party is totally possible!

❤️ Girl’s fashion hack#8: Keep Jewelry Organized While Traveling hack

Thread necklaces through drinking straws to prevent tangling – simply clasp the necklace and thread the chain through a straw.

9. Simple bachelorette party outfits at home

For a casual home party, dress whatever you feel at home if your crowd is chill and carefree.

So yes, from a tube top and denim shorts set to a billowy romper, they are all doable!

For footwear, swap the stilettos for walkable espadrille wedges or chunky low heels to feel the best.

Go for the budget-friendly retinol body cream for a mild but still noticable skin tightening effect!

I’ve been using this jar for 2 years and it works. That being said, if your skin is sensitive so I’m not too sure can you use it.

10. Enjoy the time with your girls!

So you’ve pinned down the outfit, it’s time to get the right mood for the party. If your inner voice said, “I’m too old for this shit”, ignore it!

As the saying goes “30 is the new 20”. We will never be too mature for a wild fun night once in a while. So whether you are a mom of 2 or a hot single lady in the 40s, enjoy the bachelorette party with your girls.

At the end of the day, it’s never about the outfit but the laughter that COUNTS 🙂
