1 Button Notch Lapel:
Notch Lapel (also called the “stepped lapel”) – The “notch” is the opening where the bottom of the collar meets the top of the lapel, usually at a 75 – 90 degree angle. The notch lapel is the most common lapel for a reason – it’s the most versatile of the bunch. It is most often found in single-breasted suit jackets, blazers and sport coats.
Slim Notch – A thinner version (smaller lapel width) of the normal notch. (Black Lapel’s Slim Notch lapels are 2.75 inches, roughly 0.25 to 0.5 inches thinner than our normal lapel.) Works best with a slim suit and flatters a slimmer body type.
Where To Wear: Every-day business suit, interview suit, can’t-go-wrong wardrobe staple, bar/club/dinner.
Who Should Wear: All body types. And while not a black-and-white rule, slim notch lapels will tend to flatter and maintain the proportions of a slimmer frame.
Type of Suit: Ideal for single-breasted suits, blazers and sports coats. Not recommended for double-breasted suits and tuxedos.
