The cocktail dress emerged in the 1920s after World War 2 when the idea of the working woman began to take hold. Today cocktail parties have changed a bit, but the dresses are basically following the same rules. It should be a fun and flirty dress (or skirt with a top) preferably in a finer material. It’s knee-length and has some kind of sleeve. And the neckline can be a bit party bold. Like back in the day, it’s a perfect opportunity to wear a nice hat.

Size 14-16

Two of my favorite online stores for maternity dresses are Tiffany Rose and Seraphine. They don’t have special plus size collections but some of their dresses are available in size 14-16. And they are generally top notch. High quality, trendy and/or classic elegant designs and maternity friendly. I found three plus size maternity cocktail dresses I wish were hanging in MY closet.

A sexy vintage look

Let’s get this party started with a sexy vintage look. I think this is a classic cocktail dress. It’s celebrating its history but with a modern touch. The stretch lace, trimmed eyelash skirt and cross over neckline makes it perfect for an evening cocktail party. And just look at those delicate sleeves. And let your partner know that it would look fabulous with some diamonds or pearls, *wink, wink*.

A dress for any season

This might be my favorite Tiffany Rose dress. I think I’ve looked at it at least 15 times (just waiting for the right occasion to splurge on it). O love the color. Not just because it’s beautiful but because it’s versatile. You can use this dress any season. It just works. It’s elegant and shimmering, perfect for any fancy cocktail party.

Lavender floral delight with nursing access

A lavender dress perfect for a summer cocktail party. Hopefully in a beautiful garden. The structured Ponte Roma bodice gives it that extra touch of style and grace. The belted empire waist will give you a fine silhouette all through pregnancy and beyond. Yes, you heard me right. You can use this after giving birth. It has a secret invisible zip for breastfeeding. Let’s hope for a long summer and many parties.

You all probably know about Amazon and all its millions of products. Of course, they will have some plus size maternity cocktail dresses. They have like everything else. But you might not know about Pinkblush and Motherhood Maternity. Both stores have dedicated plus size maternity collections/sections on their respective websites. And a lot at wonderful stuff for a maternity wardrobe.

A flattering and comfortable dress

A beautiful plus size dress that hugs your tummy without being tight. It comes in 7 different colors, so it doesn’t matter if you’re going to a winter or summer cocktail party. There’s a color matching any season. I would totally go for mauve. Not just because I think it’s gorgeous, but it can be worn all through the year. All though the ruffles and tulip sleeves give it a spring/summer touch.

Beautiful and up to 4XL

This is a great plus size maternity cocktail dress. You got 8 deep colors to choose from and it’s available from L to 4XL. It ticks all the boxes for being a cocktail dress. But, it’s also suitable for work, vacation, a party or why not the beach. And I really like the pockets, it’s a fun detail that gives it a little confident and relaxed feel. It’s not the fanciest (and not the most expensive either), but you can easily style it up with heels and accessories.

My maternity LBD

A great little black dress. What constitutes a LBD is what makes it so great. It works for almost any occasion. And when you have found one you like you can wear it to countless parties and events. It’s a black dress. Style it with different shoes, jewelry, hairstyles and make-up instead. Super cost effective and perfect for the maternity wardrobe.

Size 18-22

Another plus size player is Yours Clothing. They describe themselves as “a fast growing and much-loved plus size fashion retailer from the UK”. They’re selling across the world and focus on affordable clothing for women sizes 14-34. They don’t have the widest selection of maternity clothes but what they have are really nice. And you can always choose clothes that have e flexible fit. If you do, you will be able to wear them even after being done with the whole pregnancy thing.

The all-out cocktail party dress

Who doesn’t love a sequin dress huh? We all need to let ourselves sparkle a little from time to time. This isn’t sold as a maternity dress but, the loose fit design will accommodate a pretty well grown pregnancy belly. Take notice of the cool cape style sleeves and cold shoulder detail. It will make a splendid party dress for years to come.

Bump it up

This skater dress doesn’t have the traditional cocktail dress sleeve but, I thought at least one dress option should be sleeveless. It’s not like there are rules that must be followed to get in to the party. I’m sure this elegant yet cute dress will get your through the doors of any party.

A cheap but nice dress

This definitely doesn’t fall within the scope of traditional plus size maternity cocktail dresses, but all parties aren’t traditional. Let’s say it’s a modern and slightly sexy take on the formal cocktail dress. I would pull up the sleeve to make it feel more cocktaily. Maybe add some very traditional accessories like a brooch, a scarf or a hat. The right pair of shoes are of course also important. Then you’ll be ready to go.
