If you haven't bought a blazer dress yet, you absolutely need to.

The number one reason is that you can wear them a number of different ways - Saturday night out with a pair of heels and during the week with some boyfriend jeans. Better again, it's a classic piece which won't go out of style anytime soon so you'll get plenty of wear from the one item. I spotted the below Topshop long-line blazer dress online today and it's the perfect shade for autumn winter. If that's not an excuse to purchase then I don't know what it is and €80 is reasonable given the huge amount of outfit options it will provide you with. If this 'Mulberry' option isn't for you then you could go for a classic black option and this military-inspired River Island one is perfectly on trend this season. At €47, it won't break the bank and again you'll get lots of wear from a timeless piece like this. Finally, we have a third option and it's a style steal at €34 from Boohoo. Khaki has been key for 2016 and that doesn't look set to change anytime soon and again, you can wear this one as a dress, over jeans, as a jacket. The options are endless and this is one trend I am definitely buying into.
