How to use: Simply put on the thong like you would any other underwear. It's one - size - fits - most, so it should fit comfortably on most body types. Note that it's mainly for party and fun occasions, not for intense physical activities. Maintenance: You can hand - wash it in cold water with mild detergent. Avoid using bleach as it may damage the color. After washing, gently squeeze out the water and let it air dry. Don't wring it forcefully to prevent the stretchy waistband from losing its elasticity.
