I made this "regency jumper" from the Sensibility Regency Gown pattern. I adjusted it quite a bit, and added an invisible zipper instead of buttons. It fit perfectly, and was oh so comfortable.
Jumpers get a bad rap. In my opinion, they are very comfortable and allow for freedom of movement. You can change your blouse to suit your mood (all the ways I am fond of wearing it are shown in these photos). The only reason a jumper would be "frumpy" looking is if it was one of those low-waisted affairs, or if the color was drab and the materials ugly.
With the demise of my favorite, some new dresses were in order. The summer is going by quickly so I needed a very fast dress design to use. I decided not to make another Regency jumper at this time, because I was afraid I would still be bogged down in trying to decipher my specialized adjustments by the time winter rolled around.
