What makes a great plus size one piece swimsuit?
Aside from style, there are a few things to keep in mind when shopping for the perfect plus size one piece swimsuit for you, and some great tips.
Look for good lining. A well-lined suit keeps everything in place and prevents any sagging when wet, especially important in light colors.
Check the material of the clothes. Suits with a higher percentage of nylon or polyester mixed with elastane keep their shape better, dry faster and last longer, especially if you’re swimming regularly.
Consider your activity level. If you’re actually swimming or playing in the waves, look for suits with secure straps, racerback options or snap closures. If you’re just poolside, you have more freedom to prioritize style.
When in doubt, size up. Plus size one-piece swimsuits that cling too close to the body are uncomfortable and unflattering. When between sizes, always size up, a suit that fits comfortably lets you really enjoy your day.
Know your size range. Always check each brand’s specific size chart before purchasing. Sizing varies greatly across different brands, and the size chart is your best friend when shopping online.
