It's starting to get chilly outside, so now is the time to plan which coat you'll be investing in this autumn!

A good coat is essential for keeping you warm but also to complement your different outfits, so if you're going for just one style this season, take a good look at your wardrobe and work out what suits you best. 

Dog tooth was seen on the Alexander McQueen catwalk this season and it is a great way to add an interesting pattern to your wardrobe - so chic!

Checks are great for making you feel all warm and cosy as the cold weather sets in, plus they're very much on trend right now.

Autumn is all about the mac and if you need more proof, look at Emma Watson's Burberry campaign for inspiration.

All the models are wearing military coats to keep warm and they look great with some skinnies and ankle boots or a knitted dress.

Duffle coats always look adorable and you can wear them with jeans or a short tea dress for an Alexa-inspired look. Even better, go for one of this season's colour block duffles and nail two trends in one.
