It all depends on what you mean by "dire", I guess. Â
To me, an additional 1/2" in the coat sleeve is drastically too much. Â And I don't agree that 1/2" in overall coat length is inconsequential. Â It isn't to me, at least. Â But I am a fanatic about these things. Â I suppose, too, that it depends on the shape of the coat. Â A lean, columnar silhouette can look dramatically longer just by adding 1/2". Â The look of full cut coat won't be affected so much. The larger armhole, it seems to me, will still be a problem, causing the coat to "droop" under the arms and (worse) lift off the collar when you move your arms. Â That always
happens to me when I put on a coat with large armholes. Â But if it doesn't happen to you, great. Â I admit that I have never had this done to a RTW or finished coat. Â I have had it done to one or two basted coats, and all ended well. Â I do, however, remember the experience of a colleague of mine who bought a really padded suit at a great price on the assumption that he could have the pads removed. Â This he did. Â And the effect was as I described: the sides lowered, and canted inward. Â Wonderful cloth, great detailing, but the suit looked ... off.
