If I could recommend one English-language, non-fiction book on the Revolution that's accessible to a general readership yet accurate and original? Timothy Tackett's When the King Took Flight, without a doubt. As for "fashion and lifestyle" books, sorry I can't be of more help, but all the books I know that fall into that category at all are in French. But if you like political history at all--and you must to some degree, if you're interested in the French Revolution--you can't go wrong with Tackett.

For non-fiction, especially for mystery, Susanne Alleyn's Aristide Ravel series (which technically opens with Game of Patience, although the author now recommends starting the series with the third and newest book, Cavalier of the Apocalypse, prequel to the other two). Her other book, a rewriting of A Tale of Two Cities along more historically accurate lines is also not bad. Her website, by the way, can be found here: http://susannealleyn.com
