Question: Can I bring a date?
Answer: It is inappropriate to bring anyone who was not specifically invited; each additional person is a significant expense, and table seating and catering has been planned on a certain number. Look closely at how the invitation is worded. If it only has your name on it, then only you should attend. However, if it is addressed to "(your name) + guest" or to you and your significant others name, then yes both of you are invited to attend.
