Finding Your Perfect Plus Size One-Piece: A Sizing Guide
The most gorgeous plus size swimsuit in the world won't work if it doesn't fit properly. Here's what to look for when shopping for plus size swimwear:
Support Matters: Look for suits with wider straps (at least 1 inch), built-in shelf bras, or underwire if you have a fuller bust. The right support makes all the difference in comfort and confidence.
Fabric Quality: Invest in plus size one-piece swimsuits with at least 15-20% spandex or elastane for optimal stretch and recovery. Higher-quality fabrics maintain their shape and color longer.
Strategic Design: Details like ruching, color-blocking, and strategic seaming aren't just aesthetic, they create shape and definition. Don't shy away from prints and patterns, which can actually be more flattering than solid colors.
Coverage That Feels Right: Only you know your comfort zone. Whether you prefer more coverage or want to show more skin, choose plus size swimwear that makes you feel confident and comfortable.
