👉 The term "necklines" refers to the shape or configuration of a woman's upper body, commonly referred to as her dress. These lines can vary from very open and flowing to very tight and restrictive. Necklines are often used in fashion to express individual style and personality. For example, a woman with a slender figure might choose a more relaxed and fluid neckline, while someone with a slightly curvy figure may opt for a more fitted or structured neckline.
