Q. Dear Rabbi, as we talked on the phone I was granted a job interview for a much needed position. I sadly don't have a proper suit for attending that important interview. Can I acquire one during the Sefirah days?
A. Horav Shlomo Miller's Shlit'a opinion is that in need you may wear a Shabbos suit for the interview.
See question 539 regarding a new suit for Shabbos during Sefirah.
