Forget any bad photo session you may have had; after all, I wasn't there.
Show up on time. You will not feel relaxed enough for good photographs when you are rushed for your appointment and being late will only cut into the generous amount of time allotted for you.
Get lots of sleep. Go to bed earlier than usual. Do whatever you can to ensure a full nights rest. If you're tired during your session, it is guaranteed to show in your photos.
Take the time to prepare your clothes as if it were your last chance to get into this business. Bring more clothes than you need so we have plenty to choose from. Only bring clothes you want to be photographed in; I can't reshoot your photos if we pick something you don't like.
