I tend to dress to where I can always carry. But I also carry my Bear Grylls knife as well.
Having said that, I believe some of my 4" heels would be considered a weapon.... lol
But I like to rely on a heightened sense of awareness to my surroundings and my brains first and foremost. Everything else I consider accessories.
"And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war." ~ Revelation 19:11
