Adelaide has been waiting in her underclothes for something new to try on. The Shop did not disappoint and fitted her in a new false rump. This will be worn with a number of different gowns, creating a silhouette much later than that created by wide panniers.

This false rump will go under the skirt/petticoat of a Robe a la Anglaise to create the desired silhouette.
The pattern maker based this model on that described, constructed, and illustrated in The American Duchess Guide to 18th Century Dressmaking. (Listed in our Reference Section). It will certainly be lighter and easier to wear than panniers.
There is a grid provided, showing the pattern, and the book explains how to calculate the correct size and circumference of the rump pads. This was a great help when patterning Adelaide's version. It worked a treat, even with her diminutive size.
It doesn't take much to make Adelaide's waist bigger. So instead of ties on the skirt/rump, the waist band will be attached with hooks or snaps to her stays.

All the hems are hand stitched and the pads stuffed with a modern filler rather than down or cork. The pads do not have to be terribly large in order to do their job under a petticoat/skirt.

To make Addy even happier during her fitting, the knitting department had two new pairs of gloves for her to try on.
Here are some every day gloves, just to keep warm:

And a longer, more fashionable version:

The point is often folded back in portraits. To maybe allow for some needlework or scrumptious tea time treats?

Of course the salmon pink pair are Addy's favourite. She has ordered more pairs in a soft blue or gold.
All these new items were made from thrifted fabric and yarn. Even the rump pads stuffing was a thrift store find. But don't tell the ladies.
It seems that the fashion for a more prominent posterior view continues to this day, though made from stretchy fabrics and foam.
Please let us know which 18th Century silhouette you prefer. Your comments and suggestions are always welcome.
Adieu for now.
