@shopping613, you must not be tall. Tall people, or people of average height with low knees, often have a lot of trouble shopping in the non-Jewish stores. Add the cost of alterations (to any clothes, even those from Jewish stores, which already carry a heavy price tag), and tznius clothes are very expensive, especially when accounting for the fact that you are unlikely to get a shabbos outfit for very cheap (weekday is another story). (None of this is an excuse for not dressing tznius. I’m just refuting the assertation that tznius clothes are not expensive.)
