Once again, J. Crew comes with a stylish, wearable line for summer 2011. The American retailer has chosen Tasha Tilberg to model for the brand's smart sportswear collection. All-white looks and hints of black, beige and orange represent some of the main elements that describe an optimistic, urban chic style through classic and classy, yet relaxed items.

J. Crew's summer 2011 collection, featuring model Tasha Tilberg, seems to perfectly embody the idea of a timeless, yet modern dressing. In fact, the American retailer recreates, reshapes and redefines urban style by adding a special chic flair. With the smart sportswear trend being so famous across the collections this season, J. Crew gives a glamorous twist to the sporty look flawlessly mixing laid-back with elegant, good taste and practicality. There's no need for accessories, just a simple hairstyle with a sexy side parting. And a pair of comfy sneakers.

There is something utterly alluring and optimistic about J. Crew's summer 2011 collection. White blazers, white shirts, white pants, white dresses, you just cannot go wrong with an all-white look. And Tasha Tilberg totally proves that our running track outfit can be both feminine and fashionable and that the everyday classics can successfully complete an effortless appearance.

The American retailer uses the finest fabrics for its summer 2011 collection such as silk, superfine cotton and lightweight leather. Jackets, blazers, pants, dresses, boyfriend sweaters are key pieces that might become our new wardrobe favorites. Think smart dressing and invest in classic items that will never go out of style. A white maxi dress or a summer suiting in crisp linen are great choices that you can wear everywhere, at any time.

Since no wardrobe is complete without the timeless, old faithful blazer, J. Crew offers two versatile versions, in black and white. This season you are also allowed to think oversized. Whether you choose a blazer or a sweater with nautical-inspired stripes, relaxed styling is so hot. Both for attitude and clothing!

This summer it's time to switch your boring pair of pants or jeans with these bias-fly jeans from J. Crew. Absolutely enviable and ultra-modern! Match them with a V-neck toffee cashmere sweater and edgy gladiator sandals. As for windy days, the nylon trench might be your saving ticket. It is extremely light as it is inspired by the diaphanous nylon used to create real parachutes. Sporty, yet feminine due to its soft color.

Add a pop of color and brighten up your street style choosing vibrant reds and blues. The silk classic army shirt in an eye-catching poppy shade is the ultimate choice for the effortlessly chic style. Team it with modern red chino shorts and flat leather sandals for a sport-luxe appearance.
