To use this Sofia thong bikini bottom, simply slip it on like you would any other bikini bottom. Since it has an elastic waistband, it should fit comfortably. When you're at the beach or pool, enjoy the skimpy coverage and the trendy low - rise style. For maintenance, rinse it with fresh water after each use to remove salt, sand, or chlorine. Don't wring it out too harshly; instead, gently press out the excess water. Hang it to dry in a shaded area. Avoid using bleach or harsh detergents as they can damage the fabric. And remember, check the size chart before buying to ensure a proper fit.
