Anyway, I have clumped these particular years together because the fashions were somewhat alike, kind of like how there was the 'Regency' era, and the 'hoop skirt era'.
The fashions in what I will now call Late Georgian/Early Victorian were rather interesting. There is nothing particularly outstanding, and you could put the 1840's in here as well, but I find they fit in more with the early 1850's.
By now, as you will recall, we have already come through the empire-waisted dress era, and that fashion is beginning to fall by the 1820's. In 1825, they were just beginning to lengthen. Here is a good picture; you can really tell that is a transitional-type dress.
I don't know why, but I tend to view this era as completely transitional. It just seems a little awkward to not have it below the bust, but not at the waist either. Hmm.
Anyway, by the 1830's, large sleeves were trending. Huge sleeves, actually. Large puffs at the top of a tight sleeve, or, strangely, tight at the top of the sleeve with a rather large puff from the elbow to the wrist. I think the large sleeves really made the waists look very small. And maybe it is the other variation that seems really weird to me, I don't know. There were other styles as well, and one thing that is rather interesting is there were a lot of different things that were fashionable.
For the skirt, from 1825 all the way to 1855 it only continued to get larger and larger. In the particular time that I am speaking of, skirts were still rather small. By the end of the 1830's, the waists had pretty much dropped to natural waist. At least, that is what it looks like to me. The first one looks almost more like 1840's (I don't know why, it just does). The museum says it is 1838. I was close. The third one down has those weird puffs I was talking about, but they manage to make it look not weird on a mannequin.
