Waist-length jackets are a type of outerwear that typically extend to the waistline. Etons and boleros are two popular styles of waist-length jackets. Etons are tailored, single-breasted jackets with a narrow lapel and usually two or three buttons. Boleros are short, cropped jackets with an open front and often have decorative trim. Both styles of waist-length jackets are versatile and can be dressed up or down depending on the occasion.
