To use this Tia bikini bottom, simply adjust the side ties to your preferred tightness for a perfect fit. When you're at the beach or pool, it'll make you look and feel amazing. As for maintenance, after each use, rinse it in cool water to remove salt, sand, or chlorine. Don't machine - wash it as it may damage the fabric and the ties. Instead, gently hand - wash it with mild soap. Hang it to dry in a shaded area to prevent the gingham print from fading. Also, avoid contact with sharp objects that could tear the fabric. Store it in a cool, dry place when not in use, and it'll stay in great condition for many beach days to come.
