Question:
May one don a brand new suit during the Three Weeks prior to Rosh Chodesh if the sheheyanu was already recited soon after acquisition (one did not actually make a sheheyanu on the beged, but rather had them in mind when making kiddush on leil Shavuous?
Answer:
I am assuming that the suit was ready to wear at that time and didn’t need any alterations, then you were already yotza the bracha, and you can wear it for the first time during the three weeks.
