I'm bored and watching Ideal World (a UK low-rent QVC for the unfamiliar), and they're featuring this thing called the WonderWeave Wonder Wrap. It's a wrap with one arm, so half cardigan/half wrap. And you can wear it so many different ways, though most of them look like something that is neither wrap nor cardigan but some hideous combo of both.
The full line is here, along with bigger pics. And I know it's not the ugliest thing ever, and some of the ways to wear it are kind of cute, but there's a serious level of WTF to a wrap with one arm.
