Only if your invitation includes a guest. If the invitation is addressed solely to you and doesn't mention a plus-one, it's generally considered proper etiquette to attend on your own rather than ask to bring a guest.
Thanks for asking, the dress code is strictly formal. There will be no tennis shoes or jeans or slacks or slippers.
There is more than adequate parking, for a smooth transition from your vehicle to the venue, on behalf of the bride and groom there will be complimentary valet parking for all guests.
