The K.Jacket is built without the structure most tailoring relies on, which changes what a correct fit even looks like. A guide to sizing it, reading its condition secondhand, and knowing what the discount is actually for.
A well-dyed K.Jacket that feels like a cardigan is worth the extra care in sizing.
Boglioli's signature piece is the K.Jacket, a blazer dyed after it has been assembled rather than before. That order of operations is the whole point: the finished garment takes colour with a depth and slight unevenness that piece-dyed cloth does not have, and no two examples land in exactly the same place.
The line is also built without the internal structure that a conventional tailored jacket depends on. With little or nothing holding the shoulder up, the jacket takes its shape from the body underneath it, which is why it reads closer to a cardigan than to a blazer on the hanger.
The primary fit question for the K.Jacket is whether Boglioli runs small. The answer is that the question does not quite apply. A structured jacket holds a shoulder line whether or not your shoulder fills it; an unstructured one does not, so a size that felt correct in a canvassed blazer will read differently here.
The practical approach:
- Compare the listing's flat measurements to a jacket you already own and like, rather than to a label size. - Shoulder width matters less than it would on a structured jacket, and chest and sleeve length matter more. - If you fall between sizes, the larger one is usually the safer error, since a soft shoulder does not go bulky the way a padded one does.
Sleeve and body length are what will send the jacket to a tailor, so check those against your own measurements before anything else. Both are straightforward alterations; the shoulder is not.
Secondhand K.Jackets often show some variation in colour depth, and a certain amount of that is the finish rather than wear. What you are separating is inherent variation from fading, which tends to be concentrated where light and friction actually reach.
Look for:
- Shoulders and upper sleeves lighter than the body, which points to hanger or sun exposure rather than the dye. - Discolouration on the lining, which is worth asking about but does not by itself tell you the cause. - The state of the interior finishing. A jacket with little internal structure shows more of its own construction, so you can see the seams directly rather than inferring their condition.
Ask the seller for close-up photographs of the collar, the cuffs, and the seat and elbows, which are where a soft jacket wears first. Pilling on those points is normal and correctable; a thin patch is not.
Soft-shouldered Italian tailoring tends to be discounted on the secondhand market for a reason that has nothing to do with quality. It is harder to sell than a conventional blazer, because a photograph of an unstructured jacket on a hanger shows a shapeless object, and buyers who want a jacket to do structural work for them pass on it.
That is the gap you are buying into. It also means the listing photographs are unusually poor evidence, so weight the measurements heavily and the styling shots barely at all.
