Let’s be real for a second. Shopping for a plus size swimsuit coverup usually feels like a choice between two extremes: a literal circus tent or a piece of dental floss that’s somehow supposed to "flow" over your hips. It’s frustrating. You’re at the beach, the sun is hitting just right, and all you want is something that doesn't make you feel like you're hiding under a tarp. Honestly, the fashion industry has historically treated plus-size beachwear as an afterthought, but things are finally shifting.
We’ve moved past the era where "size inclusive" just meant adding two inches of polyester to a straight-size pattern. Now, we’re seeing actual design. Real thought. You want to walk from the sand to a sit-down taco spot without feeling like you’re wearing a bathrobe, right? That requires a specific mix of fabric weight, drape, and—most importantly—breathability. Nobody wants to deal with "thigh chafe" compounded by a heavy, non-breathable fabric that traps heat like a greenhouse.
Why most plus size swimsuit coverup options fail the vibe check
The biggest issue? Scaling. When brands take a size 4 pattern and just "embiggen" it to a size 24, the proportions go haywire. The armholes end up at your waist, or the neckline plunges so far it’s basically a belt. A good plus size swimsuit coverup needs to account for the fact that bodies carry weight differently. Some of us are apple-shaped, some are pear-shaped, and some are just... curvy everywhere.
I’ve spent way too much time looking at "one size fits all" labels that are, frankly, a lie. If it fits a size 2 and a size 22, it’s not actually "fitting" either of them well. It’s just a square with holes in it. Genuine inclusivity means grading patterns so the bust sits where a bust actually sits and the hemline doesn't ride up three inches in the back because of your glutes.
The fabric trap
Avoid cheap rayon if you can. I know, it’s everywhere. It’s cheap. But the second rayon touches salt water or sweat, it becomes heavy and weirdly stiff. It loses that "breezy" look instantly. Look for linen blends or high-quality crochet. Crochet is having a massive moment right now—think of brands like Eloquii or even the high-end stuff from Farm Rio. It offers texture without adding bulk. Plus, the holes in the knit allow for actual airflow, which is a godsend when it’s 95 degrees and humid.
What to look for in a functional plus size swimsuit coverup
You need to think about the transition. Are you staying at the pool all day? Then a sheer sarong is fine. But if you’re planning on hitting a boardwalk or a resort lobby, you need opacity. This is where the "shirt dress" style wins every single time.
A button-down oversized linen shirt is basically the GOAT of coverups. You can wear it open over a bikini, tie it at the waist with high-waisted bottoms, or button it up entirely to look like a person who actually has their life together. It’s versatile. It’s classic. It doesn't scream "I am trying to hide my body." Instead, it says "I am effortlessly chic and might own a boat."
Length matters more than you think
Short coverups can be a nightmare if you’re active. You bend over to grab a towel and suddenly you’re giving the whole beach a show. If you’re worried about that, go for a midi or maxi length. A floor-length caftan—the kind that makes you look like a rich widow at a Mediterranean villa—is a powerful move. Brands like Curvy Beach or Summersalt have been playing with these silhouettes lately, and the key is the side slit. Without a slit, a maxi coverup can make you look like a column. With a slit? You’ve got movement. You’ve got leg. You’ve got drama.
The "Invisible" details that make or break the look
Let's talk about waist definitions. A lot of plus-size clothing tries to "create" a waist with tight elastic. Sometimes that works, but often it just creates a "sausage" effect that feels restrictive. Look for drawstring waists instead. They allow you to decide where the cinching happens. Maybe you want it high under the bust (empire style) or lower on the hips. Control is everything.
Then there’s the sleeve situation. Wide, kimono-style sleeves are great for airflow, but they can be a pain if you’re trying to eat lunch. Ever dipped a bell sleeve into a bowl of guacamole? I have. It’s not great. If you’re planning on dining in your plus size swimsuit coverup, look for a cuffed sleeve or something you can easily roll up.
Real-world durability
Let's be honest: sand is everywhere. Sunscreen stains are real. If you buy a delicate silk coverup, you’re going to be stressed the whole time. Stick to cotton, modal, or technical fabrics that can survive a machine wash. Mesh is surprisingly durable and dries in like ten minutes, which is perfect if you’re hopping in and out of the water. Just make sure the mesh is soft; some cheaper versions feel like you’re wearing a literal fishing net, and that’s a one-way ticket to Skin Irritation City.

Breaking the "Must-Hide" mindset
For a long time, the advice for plus-size women was to "camouflage." That’s boring. It’s also outdated. The best plus size swimsuit coverup isn't a disguise; it’s an accessory. Don't be afraid of bright colors or bold, oversized tropical prints. Neon pinks, deep cobalts, and citrus yellows look incredible against sun-kissed skin.
If you prefer neutrals, play with texture instead of color. A white eyelet lace coverup is timeless. It feels expensive even if it wasn't. It’s about intentionality. When you choose a piece that reflects your actual style—rather than just picking the first thing that fits—you carry yourself differently. Confidence isn't just a buzzword; it’s the result of not having to tug at your hemline every five seconds.
Actionable Steps for Your Next Beach Trip
Stop settling for the "tent" and start looking for pieces that offer both form and function.
- Check the fiber content. Look for at least 60% natural fibers (cotton, linen) for breathability. If it’s 100% polyester, you’re going to sweat.
- Measure your "seated" length. When you sit down, most coverups hike up 3-4 inches. If you want to be comfortable at a beachside cafe, make sure the hemline accounts for this.
- Prioritize adjustable features. Drawstrings, tie-fronts, and button-ups offer more versatility for different body shapes than fixed-seam garments.
- Invest in a "hero" piece. One high-quality linen shirt or a well-made crochet tunic will last five seasons, whereas three cheap rayon sarongs will be trashed by the end of August.
- Don't ignore the armholes. If they’re too tight, you’ll be miserable. If you’re shopping online, look for "drop shoulder" or "dolman" sleeves to ensure a comfortable fit regardless of your upper arm measurement.
The goal is to spend less time worrying about how you look and more time actually enjoying the water. Find a piece that makes you feel like the best version of yourself, throw it on, and go get some sun.
