Virgin Wool Blazer Sizing: True to Size or Size Up?
Does a virgin wool blazer jacket run true to size or should I size up?
Most virgin wool blazer jackets run close to true to size, but the “right” size depends on how you plan to wear it and how structured the blazer is. Virgin wool has a refined drape and typically less stretch than knits, so a blazer that fits perfectly in the shoulders can feel snug if you regularly layer thicker tops underneath.
When true to size usually works
Choose your usual size if you want a clean, tailored look and plan to wear the blazer over lightweight layers like a dress shirt, blouse, or thin knit. A proper fit should sit flat across the chest, with shoulder seams ending right at the edge of your shoulders. The sleeves should allow comfortable arm movement without pulling at the back.
When sizing up is the smarter move
Consider sizing up if you prefer a relaxed fit, plan to wear chunky sweaters, or often find blazers tight through the upper arms or across the back. Virgin wool blazers that are fully lined or heavily structured can feel less forgiving, so an extra size can improve comfort—especially when buttoned.
A quick at-home fit check
Try the blazer on with the thickest layer you’d realistically wear. Button it and do three checks: (1) shoulders stay in place without divots, (2) you can hug yourself without strong resistance, and (3) the front doesn’t pull into an “X” at the buttons. If you see pulling or feel restriction, sizing up (or choosing a different cut) is usually better than hoping it “breaks in.”

FAQ
How should a blazer fit in the shoulders?
The shoulder seam should align with the edge of your shoulder bone, lying smooth without bumps or collapse. If the seam hangs past the shoulder or the fabric dimples, the size or cut isn’t right.
