If the majority of the clothes worn on Shabbat are special and set aside to be worn only on Shabbat and yom tovim can one mix in a minority of clothing usually worn during the week?
For example one has a special suit, tie, shoes and coat for Shabbat can he add to the outfit a winter hat worn during the week along with a warm sweater also worn during the week?
Can one do this le'hathilla or is it preferable for all the clothes to be specially designated for Shabbat/Yom Yov?
Rabbi Eli Mansour addresses the question of wearing weekday shoes:
The Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909), in his work Rab Pe’alim, addresses the question of whether one must have a special pair of shoes designated for wearing on Shabbat. He proves from a number of sources that one is not required to have a special pair of shoes for Shabbat, though certainly one should polish his shoes and make sure they look presentable for Shabbat. The Kaf Ha’haim writes that one who can afford to purchase a special pair of shoes for Shabbat should preferably do so, though this is not required according to the strict Halacha.
But I wonder if shoes are the exception.
