The triangle bra is made up of two triangular cups without any structure or underwire, which follow the natural shape of the breast. Light and flexible, it is suitable for small to medium busts looking for comfort, rather than for strong support on a daily basis.
The triangle bra gets its name from the geometric shape of its cups, without any padding or underwire. It is the most flexible style among bra shapes.
Without underwire or structure, this style does not reshape the bust: it simply supports it. There is also a triangle bra with underwire for a bit more support, and a triangle bra without underwire for maximum comfort.
The lace triangle bra remains the most sought after for dressed-up occasions, ahead of the push-up triangle bra which adds a slight lift without losing the lightness of the style.
