Not quite a hat, but more than a headband-the TURBAND. Navy blue is the color of trust, peace, and loyalty. Navy Turband is a great alternative to the Basic Black Turband -- carries the same sense of elegance and simplicity.
One size fits most. This style measures 4 1/2" at widest point on sides, 3 3/4" at narrowest point on sides, 2" wide at center knot, and 20 1/8" in circumference, fabric unstretched.
