Summary
The Sims 4has been around for about a decade now, but the swimsuits EA has given us are still more than a little disappointing. Too many simmers know the experience of putting a lot of time and energy into designing their Sims' outfits, only to struggle to find suitable swimwear.
EA’s swimwear selections are pretty basic, and don’t quite have the right look and vibes if you want your Sims to be appropriately dressed forthe next pool partyor beach day. With that in mind, we’ve scoured the internet for some of the best swim attire for Sims of all ages.

8Pride Mermaid Tails
There’s always a good reason to downloadsome pride-themed custom contentinto your game, and these adorable mermaid tails are no exception. Mermaid Sims tend to get a raw deal, as while their mermaid forms are functionally the same as swimwear, there’s not much high-quality custom content for them.
The tails that come with this download are one of the biggest sets yet for mermaids. These mermaid tails are available for Sims aged teen to elder, and have 20 different swatches with color schemes themed after a variety of different pride flags. Now your mermaids can explore the seas and enchant landlubbers while letting their true colors shine!

7Summer Olympics Set
Now all your Sims can go for the gold! Like swimwear, workout gear tends to get overlooked when it comes to custom content. While the Summer Olympics set may not be the cutest or most fashionable attire out there, it makes up for that by offering your Simspeak athletic performance.
The swimsuits included in this set are sleek, practical, and can be customized with color schemes themed after a wide variety of different real-world flags. No matter where you are in the world, your Sims can all come together through their shared passion for sport.

6Stranger Swimsuit and Bodysuit
With over 70 different solid color swatches available, the Stranger suit is an indispensable part of any CAS collection. It’s available for femme-presenting Sims aged teen through elder, which means the whole family can coordinate with matching swimsuits if you want. It’s fresh, fun, and colorful, which is everything you want in a swimsuit.
The shape and cut of the swimsuit in question is also pretty interesting, which is great since most one-piece swimsuits all sort of look identical. If you want to make your Sims rewear the same garment for different outfits, it can also be used as a bodysuit for your Sims' athletic wear.

5The Brokini
Let’s face it: the brokini is a downright goofy piece of swimwear. However, the state of masculine attire in the world of custom content is pretty dire, and swimwear is in an even worse situation. Anything that isn’t the same tired old speedos and swim trunks is welcome, which means we must embrace the brokini.
There are 20 swatches available, and they’re all in the dorkiest patterns you could imagine. This is the perfect piece of custom content for simmers who aren’t afraid to embrace the cartoony, weird vibes of The Sims in earnest. Whether your Sim has a six-pack or a dad bod, the brokini can’t gotoowrong.

4Llama Hammocks
Speedos are a dime a dozen in the Sims 4 custom content community, but they tend to come in one of two flavors. There are boring, sad speedos that resemble EA’s pathetic offerings, and there are speedos that would make the creator of Wicked Whims blush. Bizarrely, Llama Hammocks are neither.
There’s a lot of colorful and goofy patterns here for your Sims to wear, so why not have a little fun with it? The eggplants are sure to elicit a chuckle or two, but there’s plenty of other fruity prints for your Sims to sport as they frolic on the beach. It’s a breezy, fun garment that’s perfect for summer.

3Viola Swimsuit
This is a downright adorable swimsuit with a new mesh that’s base game compatible. It’s a great addition to a cottagecore Sim’s wardrobe, but you can use it for just about any fem-presenting Sim that loves ruffles. In a world where one-piece swimsuits all kind of look the same, the Viola is a welcome addition.
There are 12 swatches available, and they’re all different pastel hues in the same gingham pattern. If there’s one thing to nitpick about this swimsuit, it’s that it would have been equally cute for teen Sims. That being said, that’s a small flaw in an otherwise great piece of content.
2Hot Summer Bikini Set
Bikinis are pretty commonplace in the world of Sims 4 custom content, and most of them are simple recolors of existing meshes. The Hot Summer Bikini Set stands out not only for its delightful retro cut, but its sheer variety of swatches. This is the perfect swimsuit for a decades challenge, if you’re going for that.
While the array of solid colors is impressive, there are also some lovely patterns included among the swimsuit’s myriad swatches. They’re perfect for sunbathing in Sulani or lounging by the pool during your Sims' next summer gathering, and exhibit some of the most saturated colors ever seen on any piece of content.
1Wet & Wild Summer Swimmy Set
This is the holy grail of Sim swimwear. Whether you’re looking for swimsuits for the whole family or just want a solid set of basics to round out your CAS collection, the Wet & Wild Summer Swimmy set has you covered. There are dozens of swatches and loads of different cuts available, all for different ages and genders.
It’s hard to overstate just how much content you’re getting in this set. Just about every age group is represented, which is amazing when you consider how rare decentcustom content for younger Simscan be. If you only download one piece of custom content for your Sims' swimwear, this is probably your best bet.
