How formal or casual do you want your bridal portrait to be? Depending on the formality of your portrait, you may need to schedule a trial appointment with your hair stylist in advance of the photo session. Be sure to bring your veil and any other hair accessories you plan to wear the day of the portrait, and show the stylist photos of updos you like as inspiration. Once you've pinned the perfect 'do, snap a few photos to document the look, and schedule another hair appointment the morning the portrait takes place. Of course, if you opt for a more casual look, you may choose to wear your hair down or style it yourself -- without hairspray or a massive stash of bobby pins.
