Banjo & Matilda Natalie Imbruglia designer charity jumper

Baby it's cold outside ... so why don't you invest in a yummy cashmere jumper that will not only keep you toasty warm but also earn you good karma points? Diminutive chanteuse Natalie Imbruglia has collaborated with Aussie knitwear label Banjo & Matilda on a "Lucky" cashmere hoodie whose proceeds go to helping women suffering from obstetric fistula in third-world countries. The limited-edition four-leaf clover embellished sweater hit the B&M online store this month, so do yourself a favour and get shopping! Style and substance you ask? Absolutely. Banjo & Matilda Lucky sweater, $499.
