, you might like to try using a longer focal length lens, also positioning the camera further away from you at mid-chest level. These suggestions will help to minimise the subtle fish-eye distortion we are seeing in your full-length fit shot, and allow better judgment of garment fit and proportions.
I generally use a 36mm lens on my Fuji XT-1. This will be equivalent to 50mm on a full-frame SLR, and is said give roughly the same perspective as the human eye. A still-longer focal length could also work, although then you start losing detail due to the "slowness" of the lens.
For examples, have a look at fit shots by Claghorn, EliodA and Anden. (Plenty of others too.) You seem very receptive to good-natured advice and the above will, I believe, help you to lift your game even further on this board.
Thanks for that advice - I am pretty sure I have a 50mm lens - I'll give it a shot next time
