Denim is denim! It will never go out of fashion (thank God)!There are very few things that I don't like in denim but in fashion we should never say never!! A denim dress is one of my all time classics. You can wear it with heels for a night out or with casual sneakers for coffee.
My ideal choice for a sunny October walk in Strasbourg :-)
