My bridal shower is going to be a tea/garden party theme that will be a little more lavish compared to most of the showers that certain parts of both my family as well as FI's family are accustomed to. We would like to let people know that jeans, tee shirts and sneakers isn't exactly appropriate to wear, but my MOH thought it would be fun to add something like "Tea party attire welcome!". You would get the drift, right? Is the wording enough to keep it from being rude?
