Can someone buy a new garmet that does not need a SHEYANU(A shirt) a few days before the nine days, that will be made or tailored on the nine days and delived after the nine days or even delived on the 9 days but not worn?
As long as the purchase and acquisition is done before or after the none days there is no problem. Ideally, the delivery should be done after the 9 days as well.
The prohibition during the none days includes the purchase, acquisition, and usage of a new item. The fact that someone making or creating something for you is not included in this prohibition.
