Do I need to wear underwear for one-piece crotch shapewear

The one-piece crotch shapewear usually needs to be paired with underwear to maintain hygiene and comfort.

It is recommended to choose breathable and seamless underwear to avoid creases. The original intention of the design of the one-piece crotch shapewear is to facilitate users to use the toilet without completely removing it, but direct exposure of the crotch may cause skin discomfort due to fabric friction, especially when sweat accumulates during exercise, which may cause moisture or allergies in the perineum. Cotton or modal underwear can effectively absorb moisture and sweat, reduce direct contact between the skin and shapewear, and avoid poor blood circulation caused by prolonged compression. Some high stretch shapewear have antibacterial coatings on the inner layer, which can reduce the probability of infection, but it is still necessary to maintain cleanliness by changing underwear frequently in daily life. Special occasions or medical use shapewear may come with disposable padding. In this case, underwear can be temporarily worn, but it is necessary to ensure that the padding fits snugly and is replaced regularly. postoperative recovery patients should follow medical advice. If shapewear needs to be worn for 24 hours, doctors may recommend using medical grade breathable underwear or intermittent exposed ventilation. People with sensitive skin should avoid decorative underwear such as lace and prioritize seamless design to reduce indentation and allergen contact.
