A women’s vintage-style casual jacket should sit cleanly on the shoulders without pulling, collapsing, or sliding off. The shoulder seam (or the point where the sleeve meets the body on a raglan style) should land right at the edge of your shoulder bone, creating a smooth line from neck to arm. If the seam drops far down your upper arm, the jacket can look sloppy and restrict movement; if it sits too far inward, you’ll feel tightness across the upper back and chest.
Through the shoulders, the best test is motion: cross your arms, reach forward as if grabbing a steering wheel, then lift your arms partway. A good fit will move with you without sharp tugging at the back shoulder blades or gaping at the front. Light structure is common in vintage-inspired pieces, so expect a little shape—but not strain lines radiating from the armhole.
Sleeves should feel comfortable at the upper arm and bicep, with enough room to bend your elbow easily. The armhole matters as much as sleeve width: a too-tight armhole makes the whole jacket feel restrictive even if the sleeve looks wide enough. In a casual vintage fit, a slightly fuller sleeve can look authentic, but it should never bunch tightly when you flex your arm.
Length depends on the style: for most casual jackets, the cuff should land around the wrist bone so your hands stay free. If the jacket is meant to be worn pushed up or cuffed, the sleeve can be a touch longer—just make sure the cuff doesn’t swallow your hand when your arms are relaxed. When trying it on, wear the layer you’ll use most often (tee, knit top, or light sweater) to confirm the shoulders stay anchored and the sleeves don’t pinch.

If reaching forward or lifting your arms makes the jacket ride up noticeably, digs into the front of your shoulder, or creates strong pulling lines across your upper back, the armholes are likely too tight. You may also feel pinching where the arm meets the body even if the sleeves seem roomy.
