We just got engaged last week, and are thinking of having an informal engagement party at our house for close friends and family. Another motivator is to show off the house because we have upgraded it a lot since our housewarming party a year ago. So I'm wondering if it's ok to throw your own engagement party (definitely not looking for gifts and would mention on the invite no gifts). And also if it's ok to just send out an evite since we are looking to do it rather quickly about 3 weeks from now. Thoughts?
