@laumapret Oh it's pretty much impossible to find a dressform that is actually your shape unless you get one of those ones that are made with a 3D model of yourself. 😄 I used to have a basic one, but none of my jackets ever fit it because my torso is *so small* but it was useful for hanging and hemming skirts.
I'm pretty flexible and can use my left hand for precision work also, so I just fit on myself. If it requires enough contortion to disturb the shape, it's a lot of eyeballing, taking it off, pinning and trying it on again!
