All the "Pretty Little Liars" came together to celebrate the premiere of "PLL: The Perfectionists" and stuck around to let loose for the after-party.

It all went down Friday night at the Hollywood Athletic Club. The venue was transformed into the set of the upcoming Freeform spin-off, and featured violinists greeting guests as they passed through the mirrored entryway into the world of "PLL."

Returning "Liars" Sasha Pieterse and Janel Parrish took the lead during the night, each wearing sultry dresses to show off their curves. Pieterse sported a black and white strapless fit while Janel commanded attention in a red number with a bold matching lip.

OG "PLL" stars, including Ashley Benson and Brandon Jones were there to show their support to the cast and show creator I. Marlene King.

Before the premiere, King confirmed that Benson, who played Hanna Marin, will be directing one episode in season 2.

Once the mingling was done, everyone headed into the premiere spot which was turned into an enchanted-like forest (a scene we'll be seeing a lot of in "PLL"). Speeches were given and they didn't hold back -- even cracking jokes about the college bribery scandal.

The Blast was in on the action, and we can assure you, episode 1 of the highly-anticipated spin-off did not disappoint. Full of secrets, passion and already one murder, "Pretty Little Liars: The Perfectionists" should be on everyone's must watch list.

After the premiere, it was time for the after-party and that's when everyone really let loose.

"Pretty Little Liars: The Perfectionists" airs March 20 on Freeform.
