For an outfit that's very simple but can be smartened up or dressed down in plenty of different ways, go for a blue blazer and white jeans. Finishing with a pair of navy and white canvas low top sneakers is an easy way to add an element of stylish effortlessness to this outfit. If you're on the hunt for a cool ensemble that will take you from winter to spring, this just might be it. This combination shows that even after 50 you still have a vast array of style options.
