Borrows menswear room through the seat and thigh with a deliberate slouch.
Also called: mom jean, relaxed taper
The basics
What to know about boyfriend
Boyfriend cuts move menswear proportions onto a women's pattern: a roomy seat, a full thigh, and a gentle taper toward a hem that is usually cuffed. The slouch, the soft collapse of extra cloth at hip and knee, is the design itself rather than a fit failure. Mom jeans apply the same ease higher, pairing the roomy seat with a high rise and a slightly tapered leg.
Rigid denim, 100 percent cotton with no stretch, serves the cut best, because stiff cloth holds the slouch in shape while stretch fabric just droops. Time sets the character: rigid denim molds to your movement over months, creasing behind the knees and at the hip in a way stretch never replicates. Cuffing is functional as well as stylistic, since the leg is often drafted long on purpose. A single 2 inch cuff sets the hem at the ankle and signals the look is intentional.
Precision is what you surrender. A cut built on room cannot define the leg, and dressing it past smart-casual rarely lands. The line between relaxed and shapeless is thin. If the seat hangs more than a palm's width below your own, you have crossed it. Fit from the waist alone, let everything below stay easy, and resist sizing up, because the ease is already drafted in.

When it works well
Relaxed weekend dressing gets structure from rigid denim that holds the slouch.
Cuffed hems with sneakers or loafers finish the borrowed look naturally.
Wearers tired of stretch get denim that breaks in and molds instead of clinging.
