A formal invitation letter to the principal of a college inviting him to the fest should be sent to him in good time and should explain in brief what the fest is all about.
You start with the a greeting and following the formal way of inviting him to the event. Inside the invitation should be the date, time and the person to contact for confirmation of attendance. You can also indicate if it is a formal or semi-formal event. It is also best to include the program inside the invitation so as to give an idea about the event.
When having a formal affair then put on the invitation 'formal dress.'
The date on a formal wedding invitation should read: on the 28th of February of two thousand and ten.
A formal invitation will be in today's post. A formal gown will be required for the Senior Prom.
looks like formal invitations to me
You just say: "This is a formal event".
Same as you would write a formal invitation (except for the letter head and its formality) but you need to assure him/her that the said invitation will be sent via courier and attach the formal invitation in the email as an advance copy (you are still bound to mail it).
That's a very beautifully written formal invitation.
maybe she wants you to ask if you can come
A formal invitation letter can be completed in the business style block format. Include all of the information that would be printed on a standard invitation, the date, time, and location of the event along with an explanation of how formal the event will be, casual, business attire, formal, etc. Be sure to include the information for the recipient to follow up, the senders phone number and address. Do not include an email address as email is not appropriate for a formal invitation. A return note with a postage paid envelope for the recipient to respond such as is included with formal printed invitations can be included.
Generally, the accepted language for a wedding invitation is formal. If the wedding is going to be less formal, then the invitations should follow that example.
It really depends on how formal it is, if it is casual just a simple " Thanks for the invitation! I'll be there! Can't wait!" is fine. If its formal " Thank you for inviting me. It will be my pleasure to attend." or something along those lines. It also depends on (obviously) if you are going or not. If you are not, thank whoever invited you and make sure it doesn't sound like you don't want to go (even if you don't) like "Thanks for the invitation. I am so upset that I cannot come, but I have already made plans." would be good for something kinda casual. Try to be polite.
