As an outsider for this book, I am of two minds. This book describes how to be fashionable in Tokyo. From an American perspective, it is very restrictive and conservative, but well... that's what is fashionable for regular people in Tokyo. If you are looking for tips on how to blend in and not give offense, while having some little flair in Japan, there are some great tips that just don't carry over that well outside of Japan in some cases (in America, for instance, socks and sandals are a major no-no). I am also a man, and very little of this book is directed towards men (and what is is even more conservative and restrictive), but I am able to step outside of myself and consider other perspectives. I didn't really get much that I could use out of this, but it was an interesting look at something rather different for me.
But... let's talk about the art. I know fashion art is really quite unrealistic, with entirely unrealistic proportions involving way too many heads of height, and this book follows that convention for most of the fashion plates and examples... but it's also manga, so it uses some of those conventions for faces, and it means that you are regularly confronted with contorted, faceless, dead-eyed hell-beasts that are terrifyingly distracting from the rather banal fashion. To add to that, it's contrasted by really adorable chibi versions of the author and an emotionally-abusive cat telling her to buy things. This made for a very strange reading experience for a rather odd and somewhat uncomfortable read on a kind of a bland topic. I'm not sure what compelled me to read this, honestly, since it's so far outside of my usual wheelhouse (maybe that was why), but I am clearly not the general audience for this, and maybe it would be more helpful for people who are.
