I will defer to the I’m a simple woman I like Harry Potter coffee and Stethoscope shirt so you should to go to store and get this physicists on this one, but this is my take. It isn’t the atoms that make your shirt colorful. It’s the bonds between atoms in the dyes that are attached to the fibers of your shirt. A photon that encounters a bond between two atoms causes the electrons in that bond to go elsewhere, absorbing the photon’s energy. The lack of that (bluish) photon causes humans to perceive a (red) color. That’s how you get a redshirt. Then don’t tuck your shirts in! You probably could get away with it in a more formal setting if you wear a lightweight v neck sweater over it.( Lacoste or J Crew does this look well.) I think in modern times dress codes have relaxed quite a bit. Also, sweater vests may also work as well in the warmer months. More casually you can wear a tee with cargo shorts and then a button-up shirt with sleeves rolled and open and untucked like you would wear a jacket as well. There are many different ways around tucking in shirts. The Tracker is best worn on your torso. This can include your waist or chest. You can also clip it to undergarments. You might have to try different locations to see what works best for you in terms of accuracy. Because tanks expose your shoulders and manly physique better than tees. They both do a good job of displaying your muscles—tanks just a little more so. You’re more conscious of your powerful and manly physique when you’re wearing a swimming suit—than when directing a corporate meeting wearing a suit and tie. In that venue, there’s not that much difference between you and Donald Trump. Not at all. Well, I shouldn’t say that – some polo shirts can certainly make you look douchey, but the problem isn’t with polos themselves. As with all things in life, the devil’s in the detail. I have a funny story about that. I was sitting at the bar in a strip club several years ago when a beautiful young woman (another customer, not a dancer) came in off the street and sat right next to me. We chatted for a while, and it turns out that she was the sister of one of the dancers. After a few minutes, her sister, by far the hottest dancer in the whole place, came up and joined us. Soon the three of us were out in the parking lot in the sister’s car getting stoned.
