Such must-haves as a grey cotton blazer and light blue jeans are the ideal way to introduce some refinement into your daily fashion mix. If you want to instantly dress down your outfit with a pair of shoes, introduce white low top sneakers to the equation. This getup is a great option when spring sets it. As you pass the big 3-0, you want to start dressing maturely. That's when inspiration like this comes in very handy.
