Best Swimsuit for Your Body Type (2025 Fit Guide)

Introduction

The best swimsuit is the one that makes you feel confident. In 2025, swimwear isn’t about following one trend — it’s about finding a style that works with your body type, supports your lifestyle, and reflects your personality.

At PASSA Beachwear, we believe every woman deserves to shine. Our Thai-silk inspired motifs are placed to elongate lines, enhance curves, and celebrate natural movement. This guide helps you pick the best swimsuit for your body type, whether you’re planning a trip to Phuket, a dive in Koh Tao, or a rooftop pool day in Bangkok.

📏 How to Measure Correctly

• Bust: fullest part of chest

• Underbust: ribcage under bust

• Waist: narrowest point at natural bend

• Hips: fullest part of bottom/hips

👉 Always compare to the brand’s size chart (see PASSA’s size guide). If between sizes, order two sizes and keep the better fit.

💪 Athletic Body Type

• Traits: straighter frame, balanced shoulders/hips, toned.

• Best fits:

  • Triangle tops → create curves.

  • Ruffles, bold prints → add softness.

  • Tie-side bottoms → adjust to your hip line.

• PASSA tip: Thai-silk motifs placed diagonally enhance flow and curve illusion.

👗 Petite Body Type

• Traits: shorter torso/legs, smaller proportions.

• Best fits:

  • High-cut bottoms → elongate legs.

  • Triangle or bandeau tops → keep proportions light.

  • Monokini with cut-outs → lengthens torso.

• Avoid heavy fabrics or wide bands that overwhelm.

⏳ Hourglass Body Type

• Traits: balanced bust/hips with smaller waist.

• Best fits:

  • Halter or underwire tops → support bust.

  • High-waist bottoms → emphasize waistline.

  • Wrap one-pieces → flattering curves.

• PASSA tip: Center-placed silk motifs highlight waist elegantly.

🍐 Pear Body Type

• Traits: fuller hips/thighs, smaller bust/shoulders.

• Best fits:

  • Bandeau or embellished tops → draw eyes upward.

  • High-cut bottoms → elongate legs.

  • Rash-guard sets → balance proportions.

🍎 Apple Body Type

• Traits: fuller midsection, slimmer arms/legs.

• Best fits:

  • Plunge one-pieces → elongate torso.

  • Tankinis with ruching → soften waistline.

  • High-waist bottoms with firm bands → smooth.

• PASSA tip: Vertical motifs visually lengthen torso.

💃 Fuller Bust

• Best fits:

  • Halter or wide straps → support + comfort.

  • Underwire/molded cups → secure lift.

  • Thicker bands → prevent digging.

• Best fits:

  • High-waist bottoms with power mesh → sculpt comfortably.

  • Tankinis → versatile coverage.

  • One-piece with ruching → smooth silhouette.

• PASSA tip: Thai-silk motifs placed diagonally lengthen and flatter.

👙 Mix & Match for Every Body

• Buy tops/bottoms separately for best fit.

• Contrast colors: dark bottoms + bright tops draw eyes upward.

• Use silk cover-ups to transition from pool to café.

🌞 Thai Climate Considerations

• Choose UPF 50+ fabrics for strong sun.

• Quick-dry fabrics are more comfortable in humidity.

• Rinse after salt/chlorine, dry flat in shade.
