I am not sure if I need to get my Fiance's Dad's live-in girlfriend a corsage or not. They plan on getting married some day, and are very serious. She gets me a Christmas present every year; but my Fiance doesn't consider her "family". He likes her very much, but we have divorced and remarried families to buy corsages for. That's a lot of grandmas, moms, and step moms... His dad may be offended, or may not even realize the tradition. I'm just not sure. Our budget is tight and I am trying to save costs wherever I can. that being said, if I had an unlimited budget, I would get one for her out of kindness alone... please help.
