In case you missed the memo (yep, srsly), then we'd better fill you in pronto. Since getting some serious love on the Miu Miu Fall 2014 catwalk back in March, the lightweight rain mac has become the cool girl's new go-to. Color-popping, transparent and serious fun, these cover-ups can be worn anytime, anywhere. Sounds amazing, right? Make like Miu Miu and team a rainbow rain mac with something super-pretty like a cutesy printed dress or a pleated midi skirt and flatform sneakers. Catwalk-approved, totally wearable and 100% shoppable right now. So, now you know.
