Curtain bangs have longer pieces at the ends that lay mid-cheek to chin-length and are often fuller and heavier like regular blunt bangs. It all comes down to their length and width. OK, What Is the Difference Between Birkin Bangs and Curtain Bangs? Regardless of how you rock ‘em, the look is universally flattering on all face shapes and textures. While Jane Birkin herself wore fuller bangs in the ‘60s, the modern take is a bit wispier and has a piecey finish that accentuates your facial features. “This style of bang-while short and straight enough to make a statement-has softer, choppier characteristics to it that give them an added femininity.” “Birkin bangs have sharp corners that frame the face and are great for people who like the idea of a full fringe, but don’t want it to fully close in on their faces in a solid heavy shape,” explains Smith.
