So if a wedding dress attracts attention, why should a bride wear one to her wedding? If its immodest and men are going to see her, its immodest. There is no “but on her wedding day she can be immodest” clause in Judaism.
Ames, it probably was the cheap LOL. Honestly though, I think you looked closer because you were thinking about this topic. Its why I looked closer this Purim. I rarely notice people’s costumes normally.
Also, I have friends that are very aidel and fine who dress up. Its in the spirit of the holiday, not to be attracting. They looked fine to me.
