Lena Dunham + Allison Williams in Bikinis in 'Girls' Trailer

If this trailer made of Instagram photos is anything to be believed, it looks like the third season of 'Girls' is going to be a day at the beach. Literally. It will features writer/actress/director Lena Dunham and Allison Williams showing off their bikini bodies, which actually may be the least skin they've ever shown on the program.

The new video for the 2014 season of the popular HBO show is merely a slide show of Instagram photos taken on set, so we're not sure if they're hinting at future plot lines or merely teasers to remind everyone that 'Girls' is returning. Either way, at least one episode will apparently take place on a sand-covered beach.

You can check out Dunham and William's day watching the surf -- plus more photos from season three of 'Girls' -- in the video below.
