1. Side Seam Tab
This holds the shirt close to your hip,
which makes for a better silhouette.
2. Locker Loop + Box Pleat.
Locker loops originated from sailors on ships with plenty of hooks, but not many closets. Box pleats add freedom of movement.
3. Button down collar stays.
(Personally, I always button. It keeps my collar neat and makes a nice curve).
4. Curved Corners.
Hitting the sweet spot between sharp and casual.
5. Spare buttons.
We don’t think you’ll need them, but just in case.
