Meant 21 cm long by 14.8 cm wide.

no, you don't have to use a photo of a girl. Could be a guy and a girl, or a crowd of sexy party people drinking, or no people at all. Up to you.

It's all on the attachments that I uploaded.

If you refer to the 2 attachments, one is of the invitation that I created myself with all the details on it (Except date is now changed to Saturday 10th August), and the other invitation called All Black Mid Summer Gala is just an example of an invitation style that I like that you could perhaps draw ideas from.
