Introduction
The right plus size swimwear bottoms can be completely transformative, providing coverage, confidence, and style all at once. Whether you prefer the tummy-control benefits of a high-waist bikini bottom, the sporty versatility of board shorts, or the elegant coverage of a swim skirt, there are excellent options designed specifically for plus size bodies. Finding the right pair means you can focus entirely on enjoying the water.
What to Look For
- Fit: Swimwear bottoms should sit securely without digging into skin or rolling down in the water. High-waist styles offer core support and a retro-flattering silhouette, while side-tie briefs allow for a customizable fit. Look for wide, flat waistbands that stay in place during active swimming.
- Style: Solid colors and classic patterns like stripes or animal prints are universally flattering. High-waist bottoms with ruching minimize tummy area concerns, while swim skirts offer additional hip and thigh coverage. Mix and match tops and bottoms from the same brand for consistent sizing.
- Quality: Look for swimwear fabrics with at least 80% polyester content for excellent chlorine and sun resistance. UPF 50+ protection is ideal for outdoor swimming. Flatlock seams prevent chafing, and double-lined fabric prevents transparency when wet.
