We have all seen Aria’s (Lucy Hale) pink-streaked hair in flashbacks, but it turns out that was tame compared to her colorful Halloween costume! Check out this pic of the pint-sized beauty donning a hot pink wig and furry rainbow boots.

Lucy tweeted the pic of herself along with the line, “Throwin it back to my days as a unicorn in training.” We love that Lucy has a sense of humor about Aria’s bold style. As daring as Aria’s fashion sense apparently always has been, this looks less like one of her everyday outfits and more like a costume. Why is flashback Aria dressing up?

Could this be related to the flashbacks we will be seeing featuring the Liars’ mini-me's? Will we be seeing the girls at various points across the years? It seems like the first few episodes are going to be pretty flashback-heavy. In addition to these potential scenes, we also know the premiere will be featuring a flashback from Toby’s perspective. We’re on board with all the peeks into the characters’ pasts if we get more answers!

What do you think? Does Lucy make a good unicorn-in-training? Why do you think she’s all dressed up? Let us know in the comments below!

Catch the next episode of Pretty Little Liars on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
