Try teaming a charcoal blazer with white dress pants if you're going for a proper, classic ensemble. If you wish to immediately tone down this outfit with a pair of shoes, why not complete your look with a pair of tan suede desert boots? Keep this look in your front hall wardrobe come warmer weather, and rest assured, you'll save a lot of time getting ready on more than one morning. This combo should erase any doubts you had about wearing more mature clothes in your late 20s.
