I have several scans of fashion plates of little boys in nearly the exact jacket as this one, but alas, I cannot get my disk to run....its driving me INSANE...so I went down and picked one similar, and snapped a picture for you. This original hand colored fashion plate is from La Mode, and is titled "Costume Parisiens 1831 No. 2904" In the time, this jacket was referred to as a 'redingote'. Even tho earlier than mine here in this post, you can see the evolution of fashion in young boy's wear, especially in the skirting. Throughout the late 1820s and early 1830s the skirting was 'full'...as in, with both sides of the skirting reaching center front. Id say, with what I have seen and have here , the height of both the gigot sleeve fullness and skirt fullness reached its peak 1835-6, from then, the sleeves started to deflate and ooze down the arm, and the skirt fullness(in boys/men only) slowly faded back ....pausing at side hips for a year or two, then narrowing into what we now recognize as the tuxedo cut, or 'tails'.
As you can see, if you click on and enlarge the photo, that our jacket skirting is about midway between full-on skirting, and half skirting, ending at the hip sides. The top fullness of the sleeves have been pleated and banded down with stitching, yet this still retains earlier fashionable collar and decorative rows of buttons...........more on those grande little gems later
Weensie little flat braid was folded very cleverly into Van Dyke points and hand stitched into place.... The original 'rick rack'. Makes you wonder what clothes would look like, if they had access to the mass woven rick rack trim. Little fine details such as these, and the buttons, were what set your little boy's clothing, and social status, apart from his neighbor
