A summer beach tunic is a lightweight, loose-fitting women's clothing typically worn at the beach or poolside. The tunic serves as protection from the sun and sand, and also provides comfort and style in hot weather. Beach tunics can be made from light and airy materials such as cotton, linen, chiffon or viscose to ensure coolness and good ventilation. They usually have a loose fit, which allows air to circulate freely and gives a feeling of freedom and comfort.
