The outfit design wasn't Fluttershy's doing, though. That was all Sombra. Well more like 70% Sombra, 20% blacksmith, 10% seamstress.
Speaking of the seamstresses, I really like how their designs came out. I was going for chestnut sabino, 50s vanity gal vibes, and I think I got it down nicely. They are of course sisters, hence the similarities. Seamstress on Sombra's left is named Marigold, and on Sombra's right is named Mirabelle.
