Why wouldn't it be legal? She's still wearing pants, right? Kinda...
I honestly can't decide which is my favorite. They both have their pros, as you said, and she looks adorable in both natural colors/lighting and the purple version. I do like how the purple version makes her glowy bracelets kind of stand out a little more, but at the same time the pink of her outfit is so pretty with her brown fur. Either way, though, it's a gorgeous piece and I love the pose and the cute little tease, including the conveniently placed arm and her cheeky expression. Gorgeous work on both of them!
