1. First of all, chest is a general term belonging to the medical category, not only referring to women. If an adjective-crisp is added, it is a description of artistic conception. Crisp means crisp, or "comfortable", which is a description of sensory response, so crisp breasts are also a compliment to women's figure.
2. Milk, which is customarily considered as breast and milk, is an abbreviation of a name, such as breast augmentation, tender breast and delicate breast. This is also a compliment to women.
