What the AI looks for in Women's Swimwear Bottoms

Coverage level
Check the stated coverage (cheeky, moderate or full) and the rise, not just the size. Coverage varies widely between brands at the same size label.
Side construction
Choose fixed sides for activity. Ties are adjustable but can loosen. Tie sides slip in surf and during swimming.
Leg and waist edges
Choose covered or folded elastic edges that lie flat. Bare elastic edges dig in and wear out quickly.
Lining
The front and seat should be fully lined. Lining prevents sheerness when wet and helps the bottom hold its shape.

Brands that matter

  • Seafolly: Wide range of coverage styles, well lined.
  • Body Glove: Durable solid-color separates.
  • Speedo: Chlorine-resistant sport bottoms.
  • Roxy: Surf-ready fuller cuts.

What to avoid

  • Unlined bottoms in pale colors.
  • String sides for water sports.
  • Buying the size that matches your top when your hip size differs.
