Let's be honest – shopping for swimwear when you're above a size 12 can feel like navigating a minefield. I remember grabbing what looked like a cute one-piece last summer, only to discover the "supportive" cups were basically decorative and the fabric turned sheer when wet. Not cool. After that disaster, I made it my mission to find genuinely good options that don't sacrifice style or function.
Last year I tried 17 different swimsuits from various brands. Three had seams that ripped after two wears, five gave zero bust support, and two had such thin fabric they became transparent in water. But I found gems too – and that's what matters.
What Actually Makes Plus Size Swimwear Work
Forget those generic "flattering" descriptions. Real swimwear solutions address specific pain points:
- Banded bottoms that stay put instead of rolling down when you move
- Underwire or molded cups that lift without digging (not those flimsy foam triangles)
- 4-way stretch fabric with at least 20% nylon or polyester for chlorine/salt resistance
- Ruching or shirring that camouflages without adding bulk
- Adjustable straps that don't slip off broad shoulders
Surprisingly, many big brands miss these fundamentals. I've found smaller specialists often do it better.
Body Type Matchups: No More Guesswork
| Your Shape | Best Styles | Styles to Avoid | Brands That Nail It |
|---|---|---|---|
| Apple (carries weight in midsection) | Empire waist tankinis, ruching detail one-pieces, swim dresses | High-cut bottoms, string bikinis | Lane Bryant, Swimsuits For All |
| Pear (fuller hips/thighs) | Skirted bottoms, boy shorts, dark bottom/bright top sets | Tiny triangle tops, ultra-high leg cuts | Torrid, Eloquii |
| Hourglass (defined waist) | Underwire halter one-pieces, belted styles, high-waist bikinis | Shapeless tank suits, bandeau tops | Curvy Beach, Cupshe Curve |
| Busty (D+ cup) | Separates with bra sizing, wide-set straps, triple hook backs | String ties, shelf bras, strapless | Bare Necessities, BraStop |
If you're between sizes, always size up with swimwear. Fabric shrinkage happens, and tight seams dig painfully after hours of wear.
Tested & Approved: Best Plus Size Swimwear Brands
After trying over 30 brands, these delivered on both quality and fit:
Top 7 Performer Breakdown
| Brand | Price Range | Sizing | Standout Features | My Personal Experience |
|---|---|---|---|---|
| Swimsuits For All | $40-$90 | 12-40 | Miraclesuit tech (targeted compression), UPF 50+ | Their shirred one-piece lasted 3 summers – color barely faded |
| Lane Bryant | $70-$120 | 14-32 | True bra-sized tops (up to H cup), tummy control panels | Only underwire that didn't stab my ribs after 4+ hours |
| Torrid | $60-$110 | 10-30 | Trend-driven prints, adjustable everything | High-waist bottoms actually covered my stretch marks |
| Curvy Beach | $65-$140 | 1X-5X | Reinforced seams, quick-dry fabric | Thick enough fabric – no see-through disasters |
| Eloquii | $85-$150 | 14-32 | Fashion-forward cuts, premium materials | Swim dress made me feel chic, not "matronly" |
| Bare Necessities | $50-$160 | 32A-46K | Bra-sized precision, European brands | Finally found a 38G bikini top with actual support |
| ASOS Curve | $35-$80 | 16-30 | Budget-friendly, massive variety | Great for trendy pieces but check fabric content – some snag easily |
Watch out for Shein and Fashion Nova swim! The sizes run extremely small, fabrics pill quickly, and stitching unravels. I learned this the hard way.
Real People Swimwear Dilemmas Solved
These questions pop up constantly in forums and fitting rooms:
Q: "Where's best plus size swimwear for big busts that won't cost $200?"
A: Bare Necessities' sale section (filter by bra size) and Swimsuits For All's underwire collection. I got a DDD-supportive top for $55 last month.
Q: "Best plus size swimwear that doesn't ride up in the crotch?"
A: Look for gripper elastic along the leg openings. Torrid's Basics line and Lane Bryant's "No Slip" promise actually work.
Q: "Swim dresses that don't balloon in water?"
A: Avoid polyester-spandex blends. Nylon-spandex (like Eloquii uses) lies flatter. Also, choose knee-length over midi.
Q: "Finding best plus size swimwear for sensitive skin?"
A: Stick to chlorine-resistant fabrics (look for PBT or Xtra Life Lycra). Brands like Summersalt use eco-friendly dyes too.
The Unspoken Fit Guide Everyone Needs
Standard size charts lie. Here's what actually matters:
Critical Measurements to Take
- Underbust + Fullest Bust (for bra-sized tops)
- Waist at Narrowest Point – not where pants sit!
- Hips at Widest Part – usually 7-9" below waist
- Torso Length (from shoulder to crotch) – crucial for one-pieces
Most women measure wrong. Your swimsuit waist isn't where jeans sit – it's higher, near your belly button. Get this wrong and you'll get constant roll-down.
Shopping Hacks That Save Frustration
- Order multiples – Sizes vary wildly even within brands
- Check return policies before buying (SwimOutlet charges $7 restocking fees)
- Use codes strategically – Swimsuits For All always has 25% off first orders
- Try on with underwear – Avoids embarrassing store moments
I keep a "swim fit kit": seamless nude underwear, strapless bra, and full-length mirror. Game changer for home try-ons.
Care That Makes Swimwear Last
Rinsing in cold water isn't enough. Extend your suit's life:
| Mistake | Why It Ruins Suits | Fix |
|---|---|---|
| Machine washing | Agitation destroys spandex fibers | Hand wash in sink with Woolite |
| Drying in sun | UV rays degrade elasticity | Lay flat indoors on towel |
| Wearing under clothes | Friction causes pilling | Change at the beach/pool |
| Hot tub dips | Chlorine bleach eats colors | Rinse immediately after |
My favorite Lane Bryant suit survived 4 seasons because I soaked it monthly in suit cleaner (try Sport Wash).
When Online Shopping Goes Wrong
Returns are inevitable. Protect yourself:
- Pay with PayPal – They cover return shipping if retailer doesn't
- Photograph defects immediately – Timestamps help dispute charges
- Know restock fees – Some charge 15% (always check policies)
Last summer, I returned a $90 suit with loose threads. The brand tried refusing refund until I sent timestamped photos. Fight back!
Final Thoughts Before You Checkout
Investing in quality best plus size swimwear pays off. That $120 suit worn 20 times costs less per wear than a $50 suit worn twice.
Remember: Your swimsuit should work for YOU – not the other way around. If it needs constant adjusting or makes you self-conscious, ditch it. Life's too short for bad swimwear.
