I've had this character in my head for a while, have had her drawn three times, but only actually gave her a name a week or so ago: Lirianna. (Rolling names like that seem good for unicorns.) This is the same busty alchemist unicorn from https://www.furaffinity.net/view/29534284/ (SFW, and with some of the background), https://www.furaffinity.net/view/32002987/ (NSFW). and https://www.furaffinity.net/view/37038439/ (NSFW). Here we have her discovering that when she placed an order for a bikini, apparently somebody figured she was exaggerating...
