Greek 
Strapless
A fashion design that relies on an extra-wide band for breast support. Achieve their strength through a longer underwire that encompasses more of the breast, and cups with added padding, boning, and shaping panels. Suitable for bare-shoulder outer garments like a strapless evening gown that exposes the shoulders and chest, as low as the tops of the areola. Some convertible bras allow straps to be removed, making a strapless bra. It may have rubberized or silicone beading inside the top edge of the cup to help keep the bra attached to the breast. An alternative when an outfit would otherwise prevent a bra being worn.
