Tibi's lime green cable knit sweater will definitely give your winter wardrobe a kick. It looks more mustard in this photo but I've seen it on a couple fashion bloggers and it seems to be more of a lime green in person (or in different light). It's $126.50 (down from $253) at shopbop.com.
Not sure if this hue is for you? Test drive the look for less care of Old Navy's lime green sweater, now just $12.97 (down from $36.94).
