In our weekly roundup of the looks that are gaining fashion ground (and the ones losing their style street cred), we saw a spring-friendly skirt silhouette, the return of a very pretty plait hairstyle and one popular clothing accent that seems to have lost its sizzle.

Up: Accordion Pleats. Last September, as design houses like Alexander Wang, Céline and Proenza Schouler sent pleated dress after pleated skirt down the Spring/Summer runways, we excitedly awaited their arrival in the real world. Well, that moment is finally here. And it’s a very specific kind of folding that seems to be resonating among celebs: Dianna Agron (left) wears a Miu Miu dress featuring accordion (or knife) pleats, and other actresses including Amanda Peet and Sasha Pieterse are following her lead. Expect to see a whole lot of non-flat-front minis, midis and maxis and perhaps even a few pleated culottes this spring.

Up: Fishtail Braids. Ice cream, flip-flops and beachy plaits. Once you start spotting those things, you know warm weather is here (or at least right around the corner). After a winter in hibernation, the do is being welcomed back by Lucy Hale (center) and Jennifer Lopez, who both show off side-swept, sexily undone versions. Considering there’s a direct correlation between the fishtail and rising temps (it’s a scientific fact), this hairstyle is only going to get more and more prevalent on the red carpet … and in your Instagram feed.

Down: Peplums. Amidst the sea of crop tops that have taken over Hollywood, there was just one star doing the waist-ruffle thing this past week. And frankly, we’d almost forgotten about the once-ultra-popular trend until we saw Ashley Benson (right) wearing a peplum Alberta Ferretti dress. While we fully predict that this look will come back in the fall, you know it’s gonna be all about shrunken tops and cutouts for the next few months.
