– Q. How long do I have to wear my freshly laundered clothes before the 9 days? Can I  just leave them unfolded on the bed instead?

A. Poskim write that one hour is enough. Some maintain that one may wear a few pieces at the same time. Others are of the opinion that a few hours are necessary (Piskei Teshuvos 551: 17).

Others permit if they are placed on the ground for a similar period of time. (ibid.) Nitei Gavriel (1: 34: 10) adds that there should be some recognition on the clothing that it is not a newly fresh washed item.

Kovetz Halohos (11: 29) maintains that the clothing should be placed on the floor that has not been recently cleaned, so it would loose its status of being really clean. (see note 30 there).
