Us Weekly and Pretty Little Liars have partnered up again to bring you a sneak peek at each week’s new episode with behind-the-scenes photos. Scroll down for more on this week’s pics, and check back every Tuesday morning to see new ones!

Yes, the reveAl is happening soon. But first: Prom!

The Pretty Little Liars episode “Last Dance” airs Tuesday, Aug. 4. And while of course we’re desperate to find out who Charles, that certifiable scoundrel, truly is, we have some glam business to attend to first: what each Little Liar is wearing to the dance!

Shall we start with Aria (Lucy Hale)? As we discovered in the last episode, PLL’s resident artiste DIY-ed her dress (because of course she did). The result: a sapphire crop top teamed with a voluminous rose-print skirt and a bud-topped headband.

Hanna (Ashley Benson), a true princess to the very end, dons a dress with a plunging brocade bodice and a white ruffled skirt, cinched at the middle with a gem-embellished belt.

Emily (Shay Mitchell) rocks a body-hugging black and silver dress with some serious Maleficent vibes, made all the more so by the addition of an epic black diamond crown.

Spencer (Troian Bellisario), always the most classic of the Liars, channels an Old Hollywood siren in her velvet halter dress dipped in a gorgeous teal hue, accented by ruched detailing.

And finally, there’s Alison (Sasha Pieterse), who arrives in a sparkling cream confection, making her a true belle of the ball.

That is, until Charles shows up! Scroll down to see more behind-the-scenes pics, and tune in to ABC Family on Tuesday at 8 p.m. ET to see all the styles in action!
