I wear my badge whenever I get the chance. Since i work in a business casual environment, I dont wear it to work. But I wear an alumna lavalier instead.
We dont' wear our badges with formals, so at most, I wear it to Alumnae Association events, Chapter events/meetings, Initiation, Founder's Day, Pin Day, weddings, funerals, interviews, a nice nights out when dressed appropriately where alcohol won't be included. ADPi is very expicit about when and where we can wear our badges.
But I wouldn't have it any other way. It reminds us of the respect it deserves.
