Halocho #5 - No laundry in the 9 days

In the first 9 days of Av one does not (usually) do laundry or even wear clothes that have not been worn before. This does not apply to undergarments. Similarly one does not use fresh towels, linen or tablecloths. All the above does not apply to Shabbos. Source: KSA 122:8-9
