Over in the British suits thread, we've been meandering slightly and are in serious danger of highjacking things. So, here's a thread to discuss all things CC41 - we should also include ||O|| labels, too. I believe these are quiet well known in the womenswear scene, though I've never seen one on a piece of man's clothing. Feel free to post here, Ladies. The topic should interest you, too. CC41 refers to "Clothing Code, 1941" as part of the wartime specifications/restrictions on cloth designed to preserve and reduce waste of raw material. The CC41 label was used roughly from 1941-52 (?? please correct me by PM if wrong and I'll update this) (image to be added later) and often (usually?) has a number printed under it. We think this number refers to the grade of cloth. Ben will hopefully cross-post his Hansard evidence. Ben, we MUST make that trip to the British Library soon. HBK will also hopefully cross post his wardrobe survey. A survey of my CC41 wardrobe produced: Sadly my lab coat (white drill cotton) has a CC41 label but no designation numbers. Wool Tweed caps: 'Spec no. 206' or simply '206' (note the lack of 'X') Cotton shirt: '3025/1 X' Jacket: 'X 209A', 'X 209E' and 'X 209F' I assume that the letter following the number is some designation of colour or style (pinstripe etc). Both the 'X 209A' labels are in identical blue with white and blue double pinstripe cloths. The 'X 209E' was a grey and black crow's foot design, and 'X 209F' is a plain black flannel. Incidentally, the 'X 209E' is a Burton's suit. The Burton's label also bears the CC41 mark, and the number 'X 78E'. So it seems that Burton had their own grading system - maybe they already had a cloth in their system designated '209'? Or maybe their cloth '78' was designated '209' by the relevant Dept. I know Burton made their own cloth. Does anyone know if they made cloth for the general consumption? More confusion. Again, hopefully this thread can be devoid of too much chatter, and stick to the point of researching and collating info on this very interesting topic.
