How to Choose the Right Plus Size Swimsuit: A Simple Guide for Comfort and Confidence

Finding the right plus size swimsuit isn’t just about choosing a larger size. The best swimsuit should feel comfortable, provide the coverage you want, and help you feel confident whether you're relaxing by the pool, enjoying a beach vacation, or spending the day in the water.

At Olasia, we believe every woman deserves swimwear that fits well and feels great. Here are a few practical tips to help you choose the right plus size swimsuit.


Start With Accurate Measurements

Before shopping for swimwear, take a few minutes to measure your:

  • Bust
  • Waist
  • Hips

Swimsuit sizing can vary between brands, so relying on your usual clothing size may not always provide the best fit. Comparing your measurements to the size chart is the easiest way to find the right size.

If you're between sizes, many women prefer sizing up for a more relaxed and comfortable fit.


Consider Your Preferred Level of Coverage

Every woman has different preferences when it comes to coverage.

Some popular options include:

Full Coverage Swimsuits

Perfect for women who want extra confidence and comfort. Full coverage styles provide support while helping you feel secure during swimming and beach activities.

Long Sleeve Rash Guard Swimsuits

Long sleeve swimwear offers additional coverage for the arms while helping protect skin from prolonged sun exposure. These styles are especially popular for beach vacations, paddleboarding, surfing, and outdoor swimming.

One-Piece Swimsuits

A classic choice that provides a flattering silhouette while remaining comfortable and versatile.


Look for Supportive Features

The right design details can make a big difference in how a swimsuit feels.

Features many women love include:

  • Tummy control panels
  • Front zipper designs
  • Stretch fabric for comfort
  • Built-in support
  • Full lining
  • Adjustable coverage

These features help create a secure fit without feeling restrictive.


Choose a Style That Matches Your Activities

Think about how you'll use your swimsuit.

For Swimming and Water Activities

A long sleeve rash guard swimsuit with a secure fit and zip-front design is often a practical choice.

For Beach Vacations

Many women prefer stylish one-piece swimsuits that combine comfort, coverage, and easy movement.

For Relaxing Poolside

Look for designs that provide support while allowing you to feel comfortable throughout the day.


Understanding Rash Guard Fit

One of the most common questions we receive is:

"How should a rash guard fit?"

A rash guard should fit close to the body without feeling overly tight.

You should be able to:

  • Move your arms comfortably
  • Zip the swimsuit easily
  • Bend and stretch without restriction

A proper fit helps keep the swimsuit comfortable both in and out of the water.


Popular Swimsuit Styles for Curvy Women

Many women prefer styles that combine comfort, support, and confidence.

Some of the most popular choices include:

  • Long sleeve one-piece swimsuits
  • Zip front rash guard swimsuits
  • Tummy control swimwear
  • Full coverage swimwear
  • UPF 50+ sun protection swimwear
  • Sport-inspired swimwear designs

These styles offer a balance of function and style while providing the coverage many women appreciate.


Final Thoughts

The best plus size swimsuit is the one that helps you feel comfortable, confident, and ready to enjoy your time in the sun.

Focus on finding the right fit, choosing the level of coverage you prefer, and selecting features that match your lifestyle. With the right swimsuit, every beach day, pool day, and vacation becomes more enjoyable.
