I think attention to strange details, like wearing lipstick, certainly is a red flag, be it for ministries or even businesses. In very few instances does it really make sense-- the only one I can think of is modelling, where lipstick is often if not always necessary (and may in fact be what you are modelling). And that is it-- when churches started placing undo attention on details relating to "image", be it the church's image or even that of it's members, it often leads to focusing on things that ultimately have nothing to do with Christ.
