So here's Rhea outfits during each arc.
At the top is her before the Invasion. And she has really short hair. *I like it*
To the left of that is her Resistance outfit, the one she is seen in most of the time.
To the right of her is her turbo dueling outfit. ^-^
Below, on the left, is her when she arrived back in Standard after the Synchro Arc. *she also ditched the barrettes for a different hair ornament*
On the right, she has on a Slifer uniform because she wanted to infiltrate the Academia from the inside. So she tried to wear the uniform to blend in. *It failed*
So yeah enjoy.
