You can tailor a blazer’s sleeves, waist and length for the price of lunch. You cannot fix the shoulders — which means the shoulder is not one detail among many, it is the entire buying decision. Here is why the shoulder decides everything, what each shape does, and how to buy accordingly.

Why the Shoulder Decides the Blazer

The unfixable detail: the the-almost-everything-else-is-alterable (the sleeves, waist and length being easily altered from the how-to-wear logic — the everything-else-alterable), the the-shoulders-are-not (the shoulder alterations being difficult and expensive from the how-to-wear logic — the shoulders-not-alterable), the the-shoulder-sets-the-whole-line (the the shoulder setting the jacket’s entire line from the statement-blazers logic — the sets-the-line), the the-wrong-shoulder-cannot-be-rescued (the a bad shoulder ruining an otherwise good jacket from the how-to-wear logic — the cannot-be-rescued), the the-buy-for-the-shoulder (the buying for the shoulder and altering the rest from the how-to-wear logic — the buy-for-the-shoulder), and the reframe (the blazer shoulder as the entire buying decision — because everything else is alterable for the price of lunch, and the shoulder is not).

The Shoulder Shapes and What They Do

The shoulder vocabulary: the the-natural-shoulder (the natural shoulder following your own line, softest and most classic from the how-to-wear logic — the natural-shoulder), the the-structured-shoulder (the structured shoulder adding definition and authority from the statement-blazers logic — the structured-shoulder), the the-padded-and-strong (the strongly padded shoulders as a deliberate statement from the statement-blazers logic — the strong-shoulder), the the-dropped-shoulder (the dropped shoulder for relaxed, oversized ease from the unexpected-styling logic — the dropped-shoulder), the the-soft-unstructured (the unstructured, soft-shouldered jackets for ease from the blazer-outfits logic — the unstructured), the the-shoulder-sets-the-formality (the the shoulder deciding how formal the jacket reads from the every-occasion logic — the sets-formality), the the-strong-shoulder-balances-volume (the a strong shoulder balancing wide or voluminous bottoms from the statement-blazers logic — the balances-volume), and the the-choose-for-your-frame (the choosing the shoulder that suits your own frame from the how-to-wear logic — the for-your-frame).

The Buying Notes

Buying a blazer properly: the the-check-the-shoulder-seam (the checking the seam sits where your shoulder ends from the how-to-wear logic — the check-the-seam), the the-move-your-arms (the moving your arms to test the shoulder and armhole from the how-to-wear logic — the move-your-arms), the the-ignore-the-sleeve-length (the ignoring sleeve length, which is easily fixed from the how-to-wear logic — the ignore-sleeve-length), the the-ignore-the-waist (the ignoring a loose waist, which a tailor can nip from the how-to-wear logic — the ignore-the-waist), the the-budget-for-alterations (the budgeting alterations into the purchase from the how-to-wear logic — the budget-alterations), the the-try-it-over-real-layers (the trying it over what you would actually wear under it from the every-occasion logic — the over-real-layers), the the-a-good-shoulder-is-worth-paying-for (the paying more for a jacket whose shoulder fits from the statement-blazers logic — the worth-paying-for), and the frame (the blazer as decided at the shoulder — natural, structured, strong or dropped — bought for the seam and altered everywhere else — where the whole jacket is decided. Check the shoulder seam, move your arms, ignore the sleeve and waist, and budget for alterations).

You can tailor a blazer’s sleeves, waist and length for the price of lunch; you cannot fix the shoulders — which means the shoulder is not one detail among many, it is the entire buying decision. The shoulder decides the blazer because everything else is alterable, shoulders are not, the shoulder sets the whole line, a wrong shoulder cannot be rescued, and you should buy for the shoulder. The shapes: natural, structured, padded and strong, dropped, and soft unstructured — the shoulder sets the formality, a strong shoulder balances volume, and you should choose for your frame. Buy properly by checking the shoulder seam, moving your arms, ignoring sleeve length and waist, budgeting for alterations, trying it over real layers, and paying for a good shoulder. Where the whole jacket is decided.
