| photo of jacket alterations based on rear-view photo
As I've posted pattern reviews, I realized a photo of a garment on a body can show garment tugs and folds much more clearly than I can see it in the mirror, especially the rear view. My dress form can be useful, but it doesn't have a swayback!
And if I'm near a mirror, I've also found I stand up straighter than I do in "real life" when my posture shifts once I am no longer studying myself.
So I take digital photos of myself wearing garment, front and back, during first baste-together, and look at them in the camera. I've found digital photographs really helpful with tailored garments
