The latest trailer for the upcoming season of HBO's "Girls" has been released.

Allison Williams, who plays the role of Marnie, is seen getting ready for her wedding in the new clip, according to People.

An exclusive photo was also released on the official "Girls" Instagram page, showing Williams in a long-sleeved bohemian-style wedding dress and flower crown, with her hair styled in a relaxed braid. She appears along with co-stars Lena Dunham, Zosia Mamet and Jemima Kirke, all dressed as her bridesmaids in light purple.

For Williams' real life wedding in September, she chose a more traditional lace gown, which also had long sleeves. She told People she chose this style of dress because she's "always cold."

In the beginning of the trailer, Dunham, who plays Hannah Horvath, is seen kissing goodbye her gay ex-boyfriend Elijah (played by Andrew Rannells), while her new boyfriend Fran (played by Jake Lacy) gives them a puzzled look.

Elijah looks at Fran and asks, "What are we supposed to not do this now that you're around?" to which Fran replies, "Maybe."

Mamet, who plays Shoshanna, is seen living in Japan, where she moves to start a new job. She's seen in the clip Skyping with someone, saying, "You know how people say that you can't run away from your problems? Well I moved away from mine and it worked, so people are so wrong."

While the gal crew may look flawless in the promotional photo for the upcoming wedding on the show, the trailer suggests a slightly chaotic twist of events. Hannah worries about Marnie, saying, "She's going to be married to someone she barely knows."

In another scene, Hannah appears to battling some brutal sweat stains, while Marnie is having a meltdown about her overdone makeup. Hannah reassures her she looks "beautiful."

Season 5 of "Girls" premieres on HBO on Sunday, Feb. 21 at 10 p.m. ET.
