Here are a few that I really like:
Chadwick's Boyfriend Cardigan (19.99-34.99) - I have this one in a bright mustard-gold color and get compliments every time I wear it. I'm planning on getting it in another color, too. It's fairly lightweight, very comfortable, and I like the coverage of the longer length.
LOFT Wavy Zebra Print Cardigan (54.50) - I love the 3/4 sleeves and the rich purplish-blue color is a fun twist on the zebra pattern.
Lands' End Stripe Merino V-Neck Cardigan (95.00) - This is a bit pricey, but made of luxurious Italian-spun merino, it's bound to be super soft and comfy. The classic stripes give it a "varsity" feel.
Mossimo Black Layering Cardigan (22.99) - This is a great basic black item for your wardrobe. I especially love the 3/4 length sleeves and the buttons on the cuffs. Think of all the different ways you could wear this one!
What about you? Do you like to wear cardigan sweaters? What other items are you looking forward to wearing this fall?
