There are of course exceptions to the rule; velvets - for example - are very difficult to 'turn' (the process of pulling them inside out when you are constructing a bow tie), they are difficult to tie and they can fray, which ruins the pile and in the long run, the look of the bow. There are also some shapes that can look better pre-tied. For example, the skinny batwing which Sean Connery is famous for wearing as James Bond, does look more symmetrical and sharp as a pre-tied. However, FOR ANYTHING ELSE, you should really be tying your own bow tie. In order to give you a little bit of a refresher - here are the basics below that will cover you for most shapes.
