First up, a false rump loosely based on a few I've seen on other blogs, but largely in part to Kendra's fantastic article on skirt support:
It sits a little differently on me. My mannequin is much smaller than me and has no bum.
Second, a 1700s petticoat. I'm attributing it to the lovely tutorials by Katherine and A Fashionable Frolick this time around. Back in 2004 I made a Butterick version of a robe a la anglaise and realized that my visible petticoat was too sheer and anything else beneath it would be seen through it (I made it for Halloween, and that is very frequently winter in my area, so underthings were necessary), sending me on a trawl of the internet to find out what a "regular" petticoat would look like. I eventually came to the conclusion (somehow) that it would be exactly like the visible petticoat. I can't remember if either of these sites were involved in that particular tidbit, but they are now.
Back view over rump.
This one was a bit harder, because I sold that costume and its petticoats last year, so I could only test the false rump with an Elizabethan petticoat, since I wanted this petticoat to be levelled at the waist, but I wasn't 100% sold on the shape of the rump without a proper petticoat to put over it... I ended up making the rump smaller before sealing it up and starting on the petticoat, but I'm not entirely happy with the shape of either. They will suffice for now.
The Challenge: #23: Generosity & Gratitude
Fabric: Mystery (stash); possibly poplin (slightly stretchy) and denim-look cotton
Year: second half of the 18th century
Notions: grosgrain ribbon, thread, bias tape, poly fiberfill stuffing
How historically accurate is it? In shape only. I hand-stitched most of the petticoat but otherwise all machine done.
Hours to complete: Perhaps around 8 hours for both?
First worn: not yet
Total cost: All stash! I did pay for the materials at some point, so I'd guess around $20 max.
