Garment reference: Xirena Eloise Ruched Blouson-Sleeve Empire Midi Dress

Bodice and sleeve: Armstrong basic dress foundation. This is not an easy block to make because it requires a lot of size measurement. Unless you have all the accurate measurements on hand, I find it easier to simplify some meausurements, then adjust during fitting. Any basic women block is suitable, but I use this one because I have not use it for a long time.
Contouring: Armstrong contouring. Some reference to empire style.
Fabric: Woven. I use silk.
Note: Everything are shown in the video. You just need to change fabric and add topstitch if you want.
