Notch lapel: the everyday choice
A small V-shaped step where the lapel meets the collar. It is the most common lapel on business and everyday suits, and the safe choice for a first suit.
Peak lapel: more formal, stronger shoulders
The lapel points up toward the shoulder, drawing the eye outward so the shoulders look broader. It suits double-breasted jackets, wedding suits, tuxedos and formal events.
Shawl lapel: for the evening
One continuous curve with no step, almost always on a tuxedo or dinner jacket, often faced in satin or velvet. Wrong for the office; perfect for an evening wedding or black-tie dinner.
In short
- Office and many occasions: notch.
- Weddings, events, double-breasted: peak.
- Evening and black tie: shawl.
