Q. A kallah is getting married right after Tisha B’av. These days the custom is to make personalized sweaters for the kallah and her family/friends. Is it permitted to decorate sweaters with “iron on” letters during the Nine Days?

A. Mishna Berura (551: 14) permits the making of clothing during the Nine Days, for a wedding that will take place after Tisha Beav. See also Piskei Teshuvos (ibid, n 58) quoting Betzel Hachochmo who permits the buying of clothing for a wedding during the Nine Days, if the necessary fixing time for them is needed then. So it would be in your case.
