- Larger DDD–M busts with no T-shirt bra that gives a smooth finish under clothes
- Returning to work with nothing that holds its shape all day at DDD cup and above
- Underwire that digs into a fuller bust before lunchtime
- Standard bras scaled up — not actually built for larger cups
- Engineered T-Shirt for larger busts A T-shirt bra specifically built for DDD–M cup
- Spacer foam cups smooth and contour under anything you wear, all day, without losing shape
- Flexiwire Adaptability lifts and supports a fuller bust, moving with your changing shape without digging
- Wider band and straps Wider 4-row closure and wider 18–22mm straps on larger sizes: the structural details that make the real difference at DDD+ cup
