Imma set this one up a lil differently.

So ignore Bo even though she looks amazing I just didn't want to crop her out because this isn't my art so I wanted to make sure you could see who's art it is. Okay the person I would trust to play Lady Cadence isssss Lucy Hale.

Okay so I love love love seeing other people's fancasts. And sophie_hqlland had put Mackenzie Foy as Biana, and if she was of proper age I'm sure she'd be good but due to her age I think she'd be an amazing Lady Cadence!
Also I am in no way hating on their cast, I just wanted to give credits to where I found this person.
She would also be a second choice for Lady Cadence, not in a rude way but I do think that the other selected person is more fit.
Also this has nothing to do with kotlc but I'm watching dance moms S7: E19 AND BRO WAS BOUTTA GET CHOKED.

And we have Chiara Aurelia.

And then my personal favorite since I just love her in general and especially for this fancast is Malina Weissman.
