Question:
Am I allowed to iron a dress in the 9 days to date in?
Answer:
If ironing the dress is needed for the date it is permitted. Ironing is considered like laundering, which we don't do during the nine days, however l'tzorech mitzva it is permitted. Dating in order to get married is considered tzorech mitzva, therefore it is permitted.
Best wishes
