Mod-80, to the women, its not about attracting other men. Its about whats’ in style and whats sold. Why would a yeshiva bachur wear a Tommy Hilfiger white shirt? Why pay more for the logo? Becuase they are trying to impress other men. Its the same concept, though womens fashion is a bit more complex.
Remember, these same women will dress to impress this way for a womens only function just as much as a wedding where they will see men. Men really aren’t a factor at all.
And if this really bothered men, they wouldn’t be marrying these women. Or discussing this before marriage. “Hot Chanis” are marrying men who obviously want their wives to look like that.
