Well, it may not have strictly been for Halloween, but her outfit for fellow pop-star Ciara's superhero-themed birthday party on Saturday will give you some serious fancy dress inspo.
Behold, Yoncé as Storm from X-Men.
The 34-year-old rocked a bright white wig, ice-blue contacts and fierce leather gloves (or possibly pleather if she's still on the vegan hype).
Ciara also slayed as Cat Woman from Batman in a skin tight PVC catsuit.
The Halloween costume bar has officially been raised.
