When you buy some new clothes the last thing you think about is doing laundry. But it may be a good idea because those new clothes may not be all that clean. Some could have tried on that garment before you bought it. Lice has been reported too. What do you do?
Any new item that touches the skin including socks, activewear, shirts, dresses and especially under garments and swimwear should be washed before you wear them. Why? Because many chemicals are added to the clothes before you buy them. Bottom line is before you wear it wash it!
