Day 2 is the best for a photoshoot for me, too. I'll be wearing a different costume day 1, and won't have time for costume changes.
I've almost got Homura done! I'm currently wrestling with her blasted black collar, which took a few tries to draft a pattern for. After that, I just have to sew snaps to the black undershirt to hold it closed, do the purple diamonds on her tights and attach them to the shoes (I'm doing one-piece tights and shoes), and then make her shield. Should be done in time.
