Choosing your bridal hairstyle can be as big a challenge as picking out your wedding dress. Hair up? Hair down? Somewhere in between. And how about hair accessories? To aid you in this tough decision, here are some gorgeous celebrity hairstyles that are guaranteed to make you look and feel like an A-lister on your wedding day. Some of them are modern while others are classics guaranteed to withstand the test of time. The Sidesweep Kristen Bell turned heads at the NYC Ballet Spring Gala when she appeared with her blonde tresses in a sideswept style. The classy look captured her fringe, making her cat eyeliner more striking. For those with longer hair, Blake Lively's loose, side-swept braid would be a perfect choice for a beach or garden wedding. The Classic Updo Emma Roberts looked amazing at the Palo Alto premiere with her shoulder-grazing bob pulled into a chic updo. Expertly smudged eyeliner gave her a smoky eye that added a sultry air to an otherwise cool and classic appearance. The Bun Who says buns have to be boring? Sienna Miller achieved a pretty and carefree boho effect by letting a few layers cascade around her face. Rihanna's loose and messy bun is not only an easy style to achieve, it also lets your wedding day makeup shine. For an extra wow factor, go for Emma Watson's classic bun with its microbraid accents. The Braid There's a reason why French braids never go out of style, if the romantically long one sported by Olivia Palermo is any indication. Gigi Hadid's braided top knot is also wedding-worthy, with its sleek edges and shine. Bridal Bobs Is there any place where the bob doesn't belong? Emma Stone's beachy and carefree waves graze her shoulders, resulting in a gently tousled look that any bride would envy. Loose Waves Nothing compliments a form-fitting wedding dress like classic beach waves, so look to Sofia Vergara's relaxed and highlighted look for inspiration. If you like the idea of wearing your hair down but don't want it in your face, you can copy Joan Smalls and slick the front back with styling spray. The Ponytail Everyone loved Kendall Jenner's classic yet semi-messy ponytail, which looked chic and casual at the same time. If you're a fan of the low pony, why not part yours in the middle for a cool and sexy look a la Jamie Chung? Accessories Galore Elle Fanning was recently spotted wearing a pretty floral headpiece that would do any summer bride proud. Chrissy Teigen also added flowers to her side-swept locks for a romantic and easy to achieve look. Whatever style you choose to go for Neal & Wolf have a great range of haircare and styling products to help you achieve hair perfection on your wedding day.
