Jacket and Blazer Alterations: How to Get an Impeccable Shoulder Fit
Shoulders are the hardest area to alter in a jacket or blazer, and also the one that changes the final result the most. I explain what can and can't be corrected, and why it's worth taking it to a dressmaker before giving up on it.
Of all the alterations we do in the atelier, shoulder work on jackets and blazers is among the ones that still commands the most respect from me, even after all these years in the trade. It's the area that holds up the entire structure of the garment, and a single millimetre too much or too little shows in the fall of the whole sleeve.
"Shoulders are a jacket's skeleton. Everything else hangs from there."
What shoulder alterations are possible
When a jacket is too wide at the shoulders, it can be narrowed by taking in fabric at the armhole seam and readjusting the sleeve entry, as long as the shoulder pad and cut allow it. It's a delicate alteration, but feasible in most cases.
The opposite case — a jacket too narrow at the shoulders — is much more limited: it can only be widened if there's enough seam allowance, which is uncommon in ready-to-wear garments. That's why, before buying a fitted jacket, I always recommend trying it on calmly and paying close attention to the shoulder area: it's the hardest part to fix afterwards.
Notebook from the atelier
Before touching a single shoulder, I always try the jacket on and watch how it falls with the arms in motion, not just at rest. An alteration that looks good standing still can fail as soon as the person walks or gestures.
Sleeves: the fit that shows the most
Shortening or lengthening sleeves is one of the most common alterations and, done well, one of the most transformative for a jacket. The key is respecting the cuff button or decorative buttonholes if it has them, and keeping the proportion with the rest of the sleeve so no section is visibly different in texture or fold.
"A well-shortened sleeve shouldn't look like an alteration. It should just look like the jacket is yours."
Taking in the body without touching the shoulders
Many jackets that seem "too wide at the shoulders" actually only need taking in through the body: removing fabric at the sides and back to better define the silhouette. It's a much simpler alteration than touching the armhole area, and it often solves the problem without needing to intervene at the shoulders at all.
When it's worth altering, and when it isn't
As a general rule, if shoulder alterations exceed a third of the price of a new jacket of similar quality, it's usually more sensible to consider other options. But for a good-quality blazer, the kind they no longer make the same way, it's almost always worth investing in the fit rather than giving it up.
If you have a jacket that never quite sits right, you can contact Atelier Yvicor so we can assess it together before deciding what to do with it.
