What you’ll need:
- a collared shirt large enough for you to comfortably close its top button
- a seam ripper & needle and thread (if your shirt has a button-down collar)
Carefully cut the collar free, just below the seam that connects it to the rest of the shirt.
If yours is a button-down collar, remove the little corner buttons with a seam ripper and then sew them over their buttonholes—or wherever else on the collar you like.
Trim off any fraying threads along the collar’s bottom edge, put it on, and be instantly more dapper.
