💧 Best Plus-Size Swimwear 2025 & Style Tips

By Tellar.co.uk | 11 July 2025

Looking for plus-size swimwear that’s stylish, supportive, and confidence-boosting? You’re in the right place. This guide breaks down flattering cuts, fabric types, shopping tips, and how Tellar helps you find the perfect fit—no returns, no guesswork.

1. What Makes Great Plus-Size Swimwear?

1.1 Support & Structure

Look for built-in underwires or molded cups in one-pieces and bikini tops. Wide straps, adjustable halternecks, and control panels enhance comfort and shape retention.

1.2 Flattering Silhouettes

Square and V-necklines elongate the torso and draw attention upward.
Wrap-style and ruching across the midsection create flattering drape.
High-waist bikini bottoms define your waist and offer tummy coverage.
Longline styles extend the body line for a sleek look.

1.3 Coverage & Versatility

Choose suits with optional skirts or tonal high-waist bottoms. These allow mix-and-match options and upgrade versatility when you leave the pool.

2. Top Plus-Size Swimwear Styles (with Tellar Fit Notes)

2.1 Full-Body Swimsuit with Control Panel

Style: One-part suit with tummy-shaping fabric and slightly high neckline.
Why it flatters: Creates a sleek silhouette with support across the midriff.
Tellar Tip: Identify whether the suit runs true to size or if a size up/down is recommended for bust/hip measurements.

2.2 Underwired One-Piece with Deep V-Neck

Style: Structured bust with underwire and wide adjustable straps.
Why it flatters: Offers lift and comfort, while the V-neck elongates the neckline.
Tellar Tip: If you’re bust-heavy, Tellar may suggest a size up—even if your waist matches your usual size.

2.3 High-Waist Bikini with Ruching

Style: Full-coverage bottom and ruched or wrap-effect briefs.
Why it flatters: High waist defines your midsection; ruching camouflages and sculpts.
Tellar Tip: Choose your usual size—ruched panels tend to stretch and adapt.

2.4 Tankini with Longline Top

Style: Fitted top that covers the waist and meets high-waist briefs.
Why it flatters: Offers modest coverage with the look of a bikini top.
Tellar Tip: Most tankini tops have generous bust and hip measurements—true to size typically works well.

2.5 Swim Dress with Flared Skirt

Style: A-line mini dress with shelf bra or underwire.
Why it flatters: Skater-skirt style hides hips and thighs while accentuating the bust.
Tellar Tip: Depending on length preference, tall-sized options may be recommended by Tellar.

3. Choose the Right Fabric & Print

3.1 Fabric Textures

Ribbed fabrics: Signal structure and stretch, ideal for shaping pieces.
Power-mesh control panels: Great for tummy support without sacrificing comfort.
Recycled polyamide/lycra blends: Durable, chlorine-resistant, and swim-friendly.

3.2 Print & Color Tips

Solid dark colors (navy, charcoal, black) streamline and create length.
Strategic color-blocking draws the eye vertically, slimming the figure.
Small prints or monochrome geometric patterns are more flattering than large florals at scale.

5. Store & Brand Recommendations

Here are some plus-size swimwear options that frequently appear in Tellar’s fit tool (UK 14+):

High-Waist Bikini with Ruching: Often true to size—Tellar notes give 1 cm stretch.
Underwired V-Neck One-Piece: Run true in waist/hips—bust may need +1 size for fuller busts.
Swim Dress with Shelf Bra: Tall options get 3 cm extra length per Tellar data.
Full-Body Control Suit: Bust may feel tight—Tellar suggests sizing up if over 38″.

💡 Tip: Check Tellar’s notes—“runs small on bust” or “generous in hips”—and adjust size before you buy, not after.

6. Plus-Size Swimwear Fit Checklist

✔️ Underwire straps adjustable?

✔️ Built-in tummy control panels?

✔️ Full bust support (cups/underwire)?

✔️ High coverage across shoulder/back?

✔️ Enough leg coverage to feel confident?

7. Real-Life Styling Tips

7.1 Add a Sarong or Pareo

A lightweight sarong in neutral tones adds elegance and coverage from waist to knee.

Tellar Fit Note: Measures 160 × 110 cm—ideal for most plus-size frames.

7.2 Top with Flowy Kimono

Look for long-line kimonos with side vents and 3/4 sleeves to float over curves.

7.3 Choose Supportive Swim Tops

Sports-bikini tops with hook-and-eye backs offer secure fit during movement—great for water activities.

7.4 Sun Shirt Overlay

A boxy sun shirt with oversized buttons helps protect your shoulders and arms.

Tellar Suggestion: Size true to chest measurement for relaxed fit.

8. Maintenance & Care

Rinse after use in laundered water; hand-wash delicate ribbed panels.
Air-dry flat to keep shapes (especially underwire and power-mesh).
Avoid rough surfaces to prevent snags—important on textured fabrics.
