Product Insights
The Underbust-Seam One-Piece from Simons (59 CAD, in stock) shapes bust with removable pads for A-C and an underbust seam for D+, elongates legs via high-cut legs and underbust seam, but provides minimal Brazilian-like coverage. It stretches for comfort, recovers shape, and feels soft; requires hand wash due to some chlorine resistance. Despite a price of 59 CAD, it is the most affordable recycled one-piece at 19.99 CAD, matching boutique design but lacking ECONYL certification.
Verified claims
- Bust shaping
- Removable pads suit A–C cups. The underbust seam lends shape to smaller busts and adds some structure for larger busts; D+ cup wearers should confirm fit by trying on.
- Bottom coverage
- Minimal bottom coverage shows outer curve of derrière, like a Brazilian cut.
- Silhouette
- High-cut legs and underbust seam elongate legs and visually minimize a fuller bust.
- Value vs. peers
- At CAD 19.99, it is the most affordable recycled one-piece, with design parity to boutique brands but no ECONYL certification.
- Stretch and hand feel
- Fabric stretches enough for comfort while keeping its shape.
- Care
- Hand wash and cold-water rinse; fabric is somewhat chlorine-resistant.
- Recycled fabric
- The one-piece is made from recycled nylon.
