MW – The posuk in Tehilim 45:14 says “Kul kevodo bas melech penima, mimishbetzos zohov lvusho. This means “The prestige of the Jewish princess is her privacy – she stays within the confines of her home; she dresses (at home) in delightful clothes.” Note that this posuk, which refers to modesty of Bnos Yisroel, mentions two points: First, the tznua is predominantly at home, not in the public areas (see Rambam, Hilchos Ishus 13:11). Secondly, while at home she dresses delightfully. Although she is a great tznua, she nonetheless attaches importance to her appearance in the presence of her husband.
Kul kevodo bas melech penima is clear-cut halacha per Shulchan Aruch (73:1). Its also a clear-cut Rambam (Hilchos Ishus 13:11), Rambam (Nedarim 12:11) Bereishis Rabah (8:12), Bereishis Rabah (45:5), Bereishis Rabah, (18:2), Medrash Tehilim (128:3), Kesef Mishneh, Rosh (Kesuvos 13:17), Rosh (Shevu’os 4:2), Teshuvos Maimoniyos (Mishpatim 5) [per the Gemorah Nazir 12a], and the gemorah itself Mesechtes Yevomos 76.
I challenge you to name a godol whose wife had a business outside the home. (The Chofetz Chaim had a grocery in the back of his house that his wife tended.)
