Frankly, I would say that I am a pretty boring dresser. Most days, I usually wear khakis or jeans (khaki shorts in the warmer months) and an oxford cloth buttondown (OCBD) shirt. I have OCBDs in several different colors, and also have sport shirts in madras for the warmer months and some shirts different checks and plaids for the cooler months. However, the general equation is usually just pants+shirt=dressed.
Once the weather cools down, though, I am able to bring some more variety to my daily dress by incorportating, what I refer to as, the "third item." This is usually a sweater, a sport coat, a jacket (like a Barbour), or even a tie, but I feel like it is the essential item to completing an outfit (I do hesitate to use the word "outfit" since that is usually a word that women use, thouh I feel like I am using it in a slightly different context). This "third item" can completely change the outfit by becoming the focal point, making the pants and shirts to perform their roles as supporting players. When I am able to wear this third item, that is when I really feel like I am "dressed."
The fact is, though, that it is simply too hot to incorporate this "third item" pretty much from June through most of Septemeber. Of course one can wear a tie or blazer during these warmer months, but for the most part, it is simply not the preferable choice. Now that the temperatures are dropping, I am looking forward to making the most of my wardrobe.
