Monster Musume, other known as Everyday Life with Monster Girls, is a mature harem genre anime and manga series. Basically, the protagonist ends up hosting a bunch of half human, half animal/mystical creature ladies in his house in a NSFW manner.
One of the characters is Mero the mermaid. Mero wears "gothic lolita." Clearly this isn't lolita, but the inspiration is there as you can see with the headdress and the stereotypical anime black and white combo.
