Best Plus Size Swimwear: Why Elastic-Free Actually Fits Better

TL;DR: The best plus size swimwear doesn't rely on tight elastic and restrictive seams to create a flattering fit. onewith's beyond-seamless, elastic-free swimsuits lay flat against your body like a second skin, creating a smooth swimsuit fit without the dreaded digging, pinching, or squeezing.

Why Finding Great Plus Size Swimwear Feels So Difficult

For years, swimwear has been designed around one idea: performance in the water.

The result? Swimsuits that are constructed with tight, bulky seams that dig into your body and squeeze in all the wrong places. Many women have been told that discomfort is simply part of wearing a swimsuit.

onewith swimsuits that fit like no-show undies are here to change that. We always say "we changed swimwear so women don't feel the need to change themselves."

Because the truth is this: the most flattering swimsuit is the one that moves with your body instead of fighting against it.

Why Traditional Elastic Swimwear Can Be Uncomfortable

Traditional swimsuits use elastic bands around the waist, legs, and openings to keep everything in place. While this construction may seem supportive, it often creates issues that many women know all too well:

• Digging and pinching
• Squeezing around the hips and waist
• Bulging where elastic cuts into the skin
• Visible lines underneath clothing or coverups
• Constant adjusting and tugging

And when a swimsuit is uncomfortable, it's hard to feel confident wearing it. That's why we stopped wearing traditional swim and we're never going back.

• Lays flat on your body
• Stretches and moves with you
