Guess what? Swimsuit shopping doesn’t have to be a whole ordeal anymore. For years, plus size people dealt with limited options, sizing that made no sense, and stores that treated us like we didn’t exist. But we’re not in that era anymore. The plus size swimwear market is growing at double the rate of the total apparel market, and brands are finally showing up with real size ranges, actual construction quality, and styles that don’t look like they were designed in 2003.

The challenge now isn’t finding anything at all… it’s finding the right thing. That’s a much better problem to have, and we’re here to help you solve it.

Plus Size Swimsuit Tips That Actually Work

Here are five plus size swimsuit tips that will save you time, money, and frustration this season.

1. Shop for the Swimsuit Your Actual Summer Needs

This is the step most people skip, and it costs them every single time. Are you swimming laps three days a week? Chasing toddlers at a splash pad? Sitting poolside with a book and a drink? Attending a destination wedding in Cabo? Those are four completely different swimsuits.

If you’re an active swimmer (laps, water aerobics, open water), you need a suit that stays put. That means secure straps like racerback or adjustable styles, chlorine resistant fabric that won’t degrade after two pool sessions, and structured one pieces or high neck tankinis that won’t shift every time you push off the wall. That gorgeous tie front halter with the delicate hardware? Save it for vacation photos, not your training sessions.

If you’re more of a poolside person who wants to look good and feel comfortable, your options open way up. Bikinis, swim dresses, two piece sets, coverup friendly styles… all of it works. The priority shifts from pure function to how you feel in it.

And if you’re going somewhere specific (a resort trip, a lake weekend, a tropical birthday celebration), the setting matters. A statement one piece hits different at a boutique hotel pool than it does at a crowded water park with your entire extended family.

Shop for the swimsuit your real life requires, not the one you imagine having. You’ll actually wear it.

2. Take Your Measurements Before You Click “Add to Cart”

Plus size sizing is all over the place, and swimwear might be the worst offender. A 2X at one brand is nothing like a 2X at another. Some brands call a size 22 a “4X.” Others cap out at size 18 and still claim to be “size inclusive.” This is not your fault. It’s an industry wide mess. But you can work around it.

Before you order anything, grab a soft measuring tape and take three measurements: bust (at the fullest part), waist (at your natural waistline), and hips (around the fullest part). Write them down. Most reputable swimwear brands publish detailed size charts… use them every single time, even with brands you’ve bought from before. Sizing can change season to season.

If you’re between sizes, size up. A swimsuit that’s slightly roomy beats one that’s pulling, digging, or riding up every time you move. Comfort isn’t negotiable.

For two pieces: your top and bottom do not have to match sizes, and they usually won’t. Brands that sell separates let you optimize fit for both. That’s one of the biggest advantages of buying separates over sets, and it’s wildly underrated.

Check return policies before you buy. When possible, order two sizes so you can compare at home. Swimwear shopping online is a numbers game… give yourself options.

3. Fabric, Lining, and Support Aren’t Optional

Construction matters more in swimwear than almost any other category. You’re wearing it wet, in the sun, sometimes for hours. Cheap swimwear will let you down fast: stretched out after two wears, see through when wet, constant adjusting all day.

Look for suits with a higher percentage of nylon or polyester mixed with elastane or spandex for stretch and recovery. The fabric should feel substantial when you stretch it, not flimsy or thin. Hold it up to the light… if you can see straight through it, the lining isn’t doing its job.

Double lining through the seat and gusset is non negotiable for a suit that’s actually worth wearing. This matters especially in lighter colors and anything with mesh or cutouts.

For bust support: underwire, wide set straps, adjustable closures, and built in cups are your best friends. A well supported swimsuit is the difference between a day you enjoy and a day you spend readjusting everything every 20 minutes. Support isn’t a bonus feature. It’s the whole point.

If you swim regularly or spend time in chlorinated pools, look for suits specifically labeled chlorine resistant. Standard swimwear fabric degrades faster in pool water than saltwater. If swimming is part of your routine, the investment pays off.

4. The “Rules” Don’t Apply to Us… Ditch Them

If you were going to listen to any of these plus size swimsuit tips, it is this one. You know the rules. “Cover your stomach.” “Dark colors are safer.” “If you’re plus size, stick to one pieces.” “Horizontal stripes will make you look bigger.” We’re not doing this anymore. None of it.

The only thing that makes a swimsuit work is whether you feel good wearing it. That’s it. That’s the whole criteria.

Bold prints? Go for it. Tiny bikinis? Absolutely. Bright colors? Yes. Cutouts? We love to see it. Plus size swimwear in 2026 is delivering edgy, sexy, playful, minimalist, maximalist styles, and all of it exists for plus size bodies. Wear what you want.

What we will say: comfort matters. A swimsuit you spend all day pulling down, repositioning, or worrying about isn’t doing its job, no matter how cute it looked on the rack. Try it on, sit down in it, move around, make sure it actually works for your body before you commit. That’s not a rule. That’s just wanting to have a good time.

5. Know Where to Actually Shop for Quality Plus Size Swimwear

This is the knowledge gap that wastes the most time. Not every brand that calls itself “inclusive” carries extended sizing all the way through, and quality doesn’t always stay consistent at higher sizes. Knowing which brands actually deliver saves you hours every season.

Some brands we consistently recommend at TCF for plus size swimwear: ELOQUII (up to size 28 to 30), RebDolls (up to 5X), Torrid (up to 6X), Alpine Butterfly Swim (swim specific and size inclusive up to 6X), Adore Me, and Good American. Target and Amazon have also expanded their plus size swim offerings and are solid budget friendly options… just pay close attention to size charts, fabric content, and customer reviews before you order.

For plus size maternity swimwear specifically, PinkBlush Maternity and Yours Clothing are worth bookmarking.

Before swimsuit season hits full swing, build a shortlist of brands that carry your size range and have a track record of delivering quality. Shop that list first. You’ll spend less time frustrated and more time in the water, which is exactly where you should be.
