Kate Bosworth looked effortlessly cute while out with her boyfriend in LA. Though she was in (boyfriend) jeans, the light colors and fabrics made us think Summer. Check out her exact Alexander Wang bag and Joie sandals!

Liv Tyler really likes the tights, shorts, and stripes look. This time she made it work for the Dennis Hopper exhibit at the MOCA. She wore her stripes in the form of a fabulous blazer, her shorts were on the dressier side, and she carried a sleek Balenciaga clutch. Wonder how she’ll do it next . . .

Blake looked stunning at the Chanel Fall 2010 Couture presentation in Paris. Her Chanel chiffon dress, wavy hair, and glowing skin made for an altogether flawless combination. Louboutin heels didn’t hurt, either.

Although rompers make easy Summer throw-ons, you can also dress them up quite nicely. Kim did so with a blazer and Balenciaga bag, creating a look that could easily transition from day to night.

Diane Kruger looked fabulous in all white at the World of Calvin Klein event in Berlin. Although her shift dress was prim and proper, she added the edge we expect from her with some major platform sandals. A perfect look for Summer . . .

Kate Moss arrived at the Dorchester Hotel in London in an outfit uncharacteristic of Summer. She sported a fashionable structured leather jacket (like this one by Balmain) and black lace-up boots, looking as stylish as ever. When the weather changes, so must we!

Bright colors work so well when paired with neutral tones. Blake Lively illustrated just that while filming scenes for Gossip Girl in Paris. Her pink pants stood out, but in addition to her beige tank, oxfords, and taupe bag, the look was stylish and chic.

This is a relatively simple look for Miss Moss, and she looks great as usual. Grays, browns, and stripes add up for a classic, sophisticated ensemble, perfect for a sushi lunch in London. Sometimes the simplest things are the chicest.
