How to Shop for Swimwear Online

Buying swimwear online feels risky when you can’t try before you buy. But with the right strategies, online swimsuit shopping offers better selection, better prices, and easier returns than crowded store fitting rooms. Here’s your complete guide.

Know Your Measurements

The foundation of successful online swimwear shopping is accurate measurements:

  • Bust – Around the fullest part, over a bra
  • Underbust – Just below the bust for band sizing
  • Waist – Natural waist, typically narrowest point
  • Hips – Around the fullest part of your hips
  • Torso – Shoulder to crotch for one-piece fit

Write these down and compare to size charts for every brand—sizing varies significantly.

Reading Size Charts Properly

Don’t assume swimsuit sizing matches your dress size:

  1. Find the brand’s size chart – Usually linked on product pages
  2. Compare YOUR measurements – Not your usual size
  3. Check reviews – “Runs small” or “runs large” feedback
  4. When between sizes – Size up; swimwear stretches when wet

Evaluating Online Swimwear

Smart online shoppers assess these details:

Fabric Composition

Look for 80%+ nylon or polyester with 15-20% spandex. Avoid suits without fabric details listed—usually indicates low quality.

Construction Details

Quality swimwear mentions: lined cups, adjustable straps, underwire (if applicable), and double-stitched seams.

Customer Photos

User-submitted photos show how swimsuits look on real bodies—far more useful than professional model shots.

According to Good Housekeeping, reading multiple reviews and examining customer photos dramatically reduces return rates.
