Lay the pocket square flat on a clean surface
Fold it in half to form a rectangle
Fold it in half again if needed to match pocket size
For a square fold, fold the bottom edge up to leave a small strip showing
For a one-point fold, fold one corner toward the center, then fold the opposite side over it
For a two-point fold, fold two opposite corners toward the center
For a three-point fold, bring three corners together with the points aligned
For a puff fold, pinch the center and let the edges drape naturally
For a crown fold, fold two side corners inward, then fold the bottom up and shape the top points
Insert the folded square into the breast pocket
Adjust the visible portion so it sits neatly above the pocket edge
