In one of my previous posts, I talked about the differences between Mori Girl and Natural Kei. In this post, I'll take a look at Dolly Kei, another sister style to Mori Girl.
Personally, I find Dolly Kei is the easiest sister style to differentiate from Mori Girl. Mori Girl, even Dark Mori Girl, has more of a soft and innocent feel, whereas Dolly Kei gives off a more mature, dark, creepy feel.
Just like Natural Kei, Mori Girl and Dolly Kei can be crossed over. Although, it is much more rare to see Mori/Dolly hybrids.
