1. Underwear: 3-6 months replacement

Underwear that comes into direct contact with intimate areas is prone to residual sweat, secretions, and bacteria. Even if washed daily, the fabric will wear out over time and dirt will accumulate in the fiber gaps. It is recommended to replace regular cotton underwear every 3 months. If there is hardening, deformation, thinning of the crotch, or odor, it should be replaced in a timely manner even if it has not been 3 months; Modal and synthetic underwear, due to poor wear resistance, can last up to 6 months.

2. Bra replacement: 6-12 months

The elastic materials (such as spandex) and supporting structures (such as steel rings and shoulder straps) of bras will gradually age with wearing and washing times. For bras worn daily, if there are loose shoulder straps, deformed cups (empty or pressed), steel ring leakage, fabric pilling, etc., it is recommended to replace them every 6 months; If used infrequently and maintained properly, the maximum duration should not exceed 12 months. Sports underwear is recommended to be replaced within 6 months due to its greater tensile strength.

3. Sleepwear: 6-12 months replacement

Although pajamas come into contact with less dirt, long-term wearing and washing can cause the fabric to harden, fade, and pill, affecting the wearing experience. Cotton pajamas are prone to losing their softness due to frequent washing and should be replaced every 6-8 months; Silk, modal and other delicate materials should be replaced in a timely manner if there is obvious hooking or wear; If pajamas have a noticeable sweat odor and cannot be washed, they should be eliminated even before the replacement cycle.

4. Shapewear: replacement every 3-6 months

Shapewear relies on elastic fabrics and pressure design to shape, and elastic fibers such as spandex are prone to fatigue and aging. Frequently worn shapewear may experience a decrease in elasticity and uneven pressure after 3 months, affecting the shaping effect and health; Low frequency shapewear is recommended to be replaced every 6 months to avoid losing support due to fabric aging.

5. Special circumstances require early replacement

• Health issues: If symptoms such as skin allergies and itching in private areas occur, even if the close fitting clothing has not reached the replacement cycle, it should be replaced immediately, and old clothing should be thoroughly disinfected or discarded.

• Body shape changes: During stages of body shape changes such as weight gain or loss of more than 5kg, pregnancy, and postpartum, it is necessary to purchase suitable sizes of close fitting clothing again. Old clothing should be promptly discarded if it does not fit properly.
