Rainy days got you down? Let Alessandra Ambrosio's cute and cozy look brighten your spirits.

Diane Kruger did some shopping at The Grove in LA in her signature fisherman cap, which she spiced up via red Ray-Ban Wayfarers ($159) and a bright orange Prada bag.

Jessica Alba was spotted in LA wearing a cobalt Kate Frances blazer, red Stun sunglasses, star-print Current/Elliott jeans ($259), and killer cutout sandals, but it was her Cobra Society black tribal-print bag ($850) that had us doing a double take. This purse is dying to be toted around, and we can't get enough of the mix of leather and wool, not to mention the awesome gold logo and tassel detail. It feeds into the structured-bag trend but also has a unique edge thanks to the printed sides. Score Jessica's exact bag now and make it your go-to this Fall and Winter.

Glee's Dianna Agron spent an afternoon at the 2012 Giffoni Film Festival in Italy wearing a ladylike printed dress with cap sleeves and matching jeweled flat sandals. But, it was her red Miu Miu sunglasses that really stole the spotlight and made us take notice. Unfortunately her exact color is sold out online, but the royal blue pair ($390) is equally flashy. If you prefer something more subtle, the bronze version ($390) is also chic. To inquire about Dianna's red pair, contact Miu Miu to find out if it's available in stores. Match it up with a printed dress like Dianna, throw it on to spice up your jeans, or sport it with your bikini on the beach to stand out on the sand.
