Keep on-trend this season with some of the hottest and most beautiful hairstyles. Summer 2011 braids, twists and ponytails are relaxed and loose, yet feminine and classy. Get ready to change up your look in an instant choosing among these versatile, summer-appropriate styling options.

The warm season is all about effortless slightly messy, yet ladylike and lovely hairstyles. And summer 2011 comes with an array of styling options so flattering and easy to wear regardless the occasion. From the oh-so-famous simple, side braid and the classic pony to more complex twists, think bold this season. Transform yourself into the ultimate sweetheart and let your hair do the talking.

One of the easiest ways to upgrade you look is to choose a braid. Even though they are considered as being rather girlie, braids can also be deliciously chic and innocent. Maybe it doesn't have a high-impact vibe, yet the side braid is sensual and hot especially if you leave a few flyaways to frame your face. Keep in mind that skinny plaits are totally unflattering. You hair should look healthy and thick (Valentino, Hermès).
For a more bohemian take, the milkmaid braids are the answer (Erdem). For an edgier approach, Givenchy's Gothic version is the ticket, while for the moments when you feel stuck for style inspiration, go for those adorable thin braids as seen at Lacoste and Charlotte Ronson.

The timeless ponytail is top of the trend list this summer. Its endless versatility is undeniable whether we say glamorous or laid-back. No hairstyle seems to combine casual and elegant better than the pony. Therefore, season after season, the catwalks are awash with different versions of this old faithful. From retro ponytails as spotted at Celine and Calvin Klein, where the messy effect adds a sexy flair, to extremely shiny and refined as seen at Chanel and BCBG Max Azria, get ready to make a style statement opting for this flirty hairstyle.

Don't be afraid to flaunt your gorgeous tresses pulling them into a cute, modern ponytail. Whether you are getting ready for a hot date or a day at the office, this is the style to wear. For a more sophisticated touch, take a lock of hair and hide the elastic band. Issey Miyake or Giambattista Valli show you how to achieve this look.

Twist, twist, twist! If you find ponytails and braids boring, you can add some attitude to your summer look choosing a twisted style. And there are so many sources of inspiration both for casual and formal occasions. In fact, this season's twists are so versatile and can perfectly embody the all-out glamour, but also the super sexy, fun casual style.

At Phillip Lim, the side twist adds a fresh and nonchalant feeling, while at Gucci, the twisted knot is so chic and modern. Sharpen up your style with a severe, slicked twisted updo as seen at Yves Saint Laurent or make a real red-carpet staple choosing the minimal 'do as spotted at Donna Karan. Difficult you say? Not at all. Just make a side parting and a ponytail rolled into itself. Next, use pins in order to keep the twist into place.
As for the Luca Luca 'Yacht Knot', start by making loose waves using a large-barreled tong. Then, part your hair and section off the top and bottom. Next, twist both top sections back, pin them into a knotted bun, and wrap the remaining section around it.
