During the Victorian era, if the tea party was to be held in the garden, invitations were sent out with a special mention that the guests need to come wearing hats. Sometimes, guests even got their own cups for such gatherings.
Of course, nowadays, to go to such extremes will be considered too much, still you can do a lot of other things while arranging such an event. Here are some interesting ideas from which you can take inspiration.
The invitations for the party should be sent at least two weeks in advance. The invitations should have designs, which remind the people of that era. A good design for the invitation can be a colorful peacock, which was considered to be a symbol of beauty by people of the Victorian era.
While sending the invitations you can put in a request to your guests to RSVP a week before the actual event so that you can plan for everything, be it the food, party setting, etc., accordingly.
You can either make the tea yourself or keep some loose tea bags in an attractive box for your guests. The etiquette says that the cups of the guests should never be empty at any point of time during the event, so if you have a large gathering, let the guests make their own tea.
These parties are classy affairs, so make sure everything about the event be it silverware, tablecloths, or table centerpieces reflect high society living.
This in no way means that you feel pressurized to keep everything prim and proper. After all, you have kept this party to reconnect with your close ones, right? So simply enjoy yourself and see to it that your guests have a gala time too.
