A mulmul cotton saree is a lightweight, breathable, and soft cotton saree, often called "muslin" or "mull," known for its comfort, especially in hot weather. It is made from finely woven yarns that give it a "woven wind" feel, making it light and airy. Historically, this fabric was a luxurious and prized export from India, and it continues to be a popular choice for its elegance and practicality for everyday wear, formal events, and humid climates.
