Gant Rugger Solid Oxford, $116

On Valet Magazine's "Ask Valet" section, a reader posed a question that we all have wondered at least once: Why are the very top and bottom buttonholes horizontal, and not vertical like the rest of the buttonholes on the shirt? No, it's not an accident on the manufacturing tip, but actually a practical feature. The holes are sewn horizontally so that the buttons can endure more stress from pulling/movement than the others without stretching out the shirt or the hole itself. That, along with some reinforcements like extra stitching with a thicker thread, makes sure buttons don't go flying all over the place.
