Ooh, gosh, I didn't mean to kill it!
I must be Susan the Thread Slayer today. I was already feeling majorly guilty for giving an honest answer on an author blog to a question along the lines of "Like my new cover, or is it too much mantitty for your taste?" (I went all historical costuming pedant. Picture my little lecturette on rifles vs. muskets from Natter, only in the form of, "If relatively low-budget productions like made-for-TV movies can get historical costumes right, why can't art departments for romance publishers?") That was two hours ago and the previously active comment thread is dead, DEAD, I tell you! Part of me feels guilty...but, she asked! If she hadn't, I would've gritted my teeth and kept my mouth shut.
ETA the author knew the costuming was inaccurate, but said it didn't bother her the way it did when something similar had happened on a previous cover because she liked other elements of the image so much. And I said inaccurate costuming would never keep me from buying a book, it just bugged my inner pedant.
