Red carpet trends - accordion pleats, fishtail braids

Do you want to know the looks that are gaining fashion ground? Accordion pleats and fishtail braids are trending on the red carpet.

People.com presents a weekly roundup of the looks that are trendy right now:

* Up: Accordion Pleats: It's a very specific kind of folding that seems to be resonating among celebrities - Dianna Agron was seen in 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. After a winter in hibernation, the do is being welcomed back by Lucy Hale and Jennifer Lopez, who both showed off side-swept? this hairstyle is going to get more and more prevalent on the red carpet.

Down: Peplums: One had almost forgotten about the once-ultra-popular trend until Ashley Benson (right) wore a peplum Alberta Ferretti dress. While the look will come back in the fall, it will be all about shrunken tops and cutouts for the next few months.
