It is getting cold and those light bomber jackets you have been wearing are no longer going to be sufficient for the stronger winds and even snow that has been appearing as of late.
Trench coats are both stylish and will also provide you that additional fabric to keep you warm. They come in many colours, but tend to have the key components of length as well as large buttons. Although, they tend to not come along with a hood so make sure you have a hat to pair with the jacket when it gets especially cold!
What does your pair look like? Or are you not interested in this particular style?
