My maid of honor wants to throw me a small bridal shower. I told her I did not want one because I did not want to put a financial strain on her or the other bridesmaids who are all in there early 20s without career jobs. She insisted so I am trying to help her find ways to make it very affordable. I offered my apartment as the venue, we would do it inside my place is 2 bedroom about 750-780 sqft so pretty small. She suggested we keep the guest list small (6 bridesmaids and couple of my other girl friends) so maybe 20 people or less. Do we have to invite our families, mom, mother in law, aunts etc or can it just be a small get together? I do not want to make anyone feel offended and I am not really sure about bridal shower etiquette.
