i can take a wild guess that those that don't like Lulu's style generally dislike Goth Style altogether, or don't know any goth people...
i myself have a Trenchcoat that straps and buckles closed like a straight-jacket and trails about a foot and a half behind me when i walk, i get strange and sometimes even hateful looks when i wear it, i guess those people are some of the same that dislike Lulu's awesome as hell dress... and yes i would so wear that dress too if i had one...
Goth Style on a Black Mage just seems to make perfect sense to me...
