We’re looking to host a formal wedding outdoors on a gorgeous private estate. The guests will receive a weekly schedule with dress code suggestions beforehand so they know how casual or formal all the events leading up to the wedding will be, as well as the wedding itself (we have several dinners and events planned during the week for guests who would like to join). We are making the wedding the most formal of the events, but wondering if a black tie is not appropriate for an outdoor wedding? Mainly, I’m wondering how etiquette lies in requesting a higher level of formality for an outdoor wedding and reception. Or are there ways to increase the formality of an outdoor wedding to make it appropriate? Family will all be in gowns, but wondering what level of formality is appropriate to mention to guests?
(Details: Ceremony at 5 on grassy area, reception at 6:30 on floored area, live music and performances, served meal, full liquor, pool, pool hall, no wedding party, invites were gilded edges w gold foil print)
TLDR - What are the qualities that make an outdoor wedding formal? How do I formalize an outdoor wedding?
