thought id share this here. About 8 years ago, i bought a cooper g-1 (milspec/real mouton collar). i ordered and received a size 42r to fit my 44 in chest. i liked the jacket but it was massively oversized. perhaps it was mislabeled but id say id say it was at least 3 sizes too big (50) and unwearable. it sat in the wardrobe for a long time and i periodically thought about selling it and rebuying a smaller size or trying to find a swap somewhere. at the weekend i had a brainwave and decided to try and shrink it. i decided from the outset that if i destroyed the jacket, i would be no worse off than i was having an unwearable jacket and would live with it. i zipped it up and closed all the buttons. i then threw it into the electric shower and soaked it thoroughly inside and out at the hottest setting. i then threw it into the tumble dryer (leather out) for a half an hour at the hot setting. after 30 mins the face of the leather was fairly dry but the inside was still quite wet. i then turned it inside out and blasted it for another 45 minutes. THE RESULT: 100% Success it now fits perfectly and is probably 3-4 sizes smaller. i mighta measured wrong but it seems to be 10cm narrower pit to pit across the front when flat, and about 8cm shorter. the arms feel tighter (good) but dont seen to have lost much length (also good) An unexpected bonus is that the pebbled effect of the goatskin has been amplified as the leather contracted and now looks much better. unfortunately, i didnt take any pictures before but will try and put some afters up later.
