Revamping shirts and 'armies'

First pic is of me wearing black linen shirt with black cotton armie underneath about a year ago and 4 stone heavier.

Then follows pics of armies too big on, then made smaller, the linen shirt made smaller with some complicated darts.  Lastly a couple of shirts made smaller simply by taking in sides 3" each doen to bust or waist then leaving flare out of original size at hip level.
