A romantic hairstyle should always look soft and touchable (even if it is actually lacquered with hairspray). The first step towards achieving this effect is to evaluate your haircolor. It should look pretty and natural, never harsh or artificial.
The most likely stumbling blocks are shades of blond that are too light, yellow, or brassy, or burgundy red haircolors never found in nature. Now it may take a number of hours in the salon to end up with your ideal "natural" look, but it should look as though you were just lucky enough to be born with such a pretty haircolor full of natural highlights.
When I envision romantic hair, the first image that comes to mind is the long flowing curls of a pre-Raphaelite beauty. The women in the pre-Raphaelite paintings embodied an innocent sensuality that is a lovely look for a bride.
They wore their hair long and loose in soft waves or curls, which is a great hairstyle for a bride with long enough hair. Pull back little twists on each side of your head. This will get the hair out of your face, and will give you a place to anchor your veil and bridal hair jewelry.
Keep your accessories simple; a few pearl hairpins or a dainty wreath look lovely with this hairdo. You know your hair best; if you are getting married at a hot and humid time of the year, beware of the possibility of an attack of the frizzies!
Another romantic wedding hairstyle is a soft chignon or a loose bun. These styles look even more romantic if the hair is curled first and then loosely secured. It should look as though you could release a bobby pin and your whole beautiful mane would cascade down your shoulders. (Remember that this is only the look that you are going for; it may take dozens of bobby pins to actually pull it off.)
A few soft and wispy tendrils can be left loose around the hairline and the nape of the neck, as long as it looks natural. Avoid at all costs the contrived spiral curled tendrils that will make you look like you are headed to the junior prom.
Less often seen, but no less pretty, is a well-executed braid. Once again, this will look the most romantic if the hair is made wavy before the braid is woven (kudos to you if your hair is naturally wavy). The braid should not be pulled too tightly or look too perfect.
The most modern take on a braided wedding hairstyle is to have a few tiny braids on each side of the head that are then woven into the main braid. For your bridal hair jewelry, consider weaving a small strand of crystals into the braid to catch the light.
Even short haired brides can achieve a romantic look for their wedding. Once again, the key is to create a style that is soft and wavy. Chin or shoulder length hair can be gently tousled to create a halo of soft waves around your face. It is a look that is both timeless and fresh, making it an ideal wedding hairstyle.
Whether your hair is short or long, straight or curly, it be made to look pretty and feminine for your wedding day. These romantic hairstyles are a wonderful complement to any style of wedding gown, and will look beautiful in your photographs.
