So this is new: Olivia Palermo, attending the premiere of new biopic Yves Saint Laurent last night in New York, had a bit of a moment in what we can only call a slime-green midi skirt (well obvs we could call it other things, but slime is good, no?). It's all about the mix. Palermo's trick is to team her offbeat bottom half with a sleek white jacket and some major patterned accessories for a combo that's fresh. The effect? Less monstrous, more super-foxy. 

After another single-item fashion overhaul? See how Jourdan Dunn makes summer's board shorts look amazing.
