i am also in shidduchim and im dressing up and i dont care what people think. (not talking tznius wise….) my entire family dresses up with a theme (my parents included) so i think it shows how close a family we are and that family is important to me!
but if you want it to be easy to take off…. how about a doctor? you wear a doctors lab coat, a stethescope (sorry i dont know how to spell that…) etc and this way you just slip off the lab coat and VIOLA you are dressed like always!
or you could be a chef… wear a white short jacket over clothes and an apron and chefs hat… same idea you can just slip it off….
