I'm not sure what you mean by the new jacket -- I just got my maternity DEU's a few months ago, and all I got was a wool cardigan and the heavy overcoat as far as 'jacket' type things go. To get the old one, you'd have to find someone willing to give them up -- but as they were issuing them out until about a year or two ago, there should be some people around who have them still.
All of the maternity gear is unattractive, but isn't that to be expected?
