This ensemble suggests that it is totally worth investing in such smart menswear pieces as an aquamarine double breasted blazer and dress pants. Does this ensemble feel all-too-classic? Let a pair of tan leather derby shoes spice things up. So as you can see, this combo is a really good option, especially for weird fall weather, when the temps are starting to drop. As you pass the big 3-0, you want to start dressing with more sophistication. In this case, ensembles like this are a tested option.
