The strange smell in sleepwear can be caused by a variety of factors. One common cause is the accumulation of sweat, body oils, and dead skin cells on the fabric, which can create an unpleasant odor over time. Additionally, using certain detergents or fabric softeners that leave a residue on the sleepwear can also contribute to the strange smell. In some cases, the material of the sleepwear itself may have a natural odor that becomes more noticeable over time. Regular washing and proper care can help eliminate or prevent these odors in sleepwear. **
