Formal or Casual Wedding Invitation Wording

There is nothing wrong with formality, but it's just not you. You are looking for a more modern wedding invitation or perhaps even a casual wedding invitation with a beach wedding invitation theme. Or perhaps you are paying for this wedding and you want an invitation that reflects your independence.
Formal wedding invitation wording, there are some rules of wording
that are appropriate:

1. Spell out every word, even the date and year. Street, not St.
Road, not Rd.
2. Use Roman numerals in titles, such as Scott Edward Smith
III. Do not use "3rd" or "third".
3. For weddings in a church, say "request the honour of your
presence". For non-religious weddings, say "request the pleasure
of your company".
4. Write out full names. Do not use initials.
