This cassock was just wide enough but was too short. Fortunately my wife is a good seamstress and had some ideas.
The bottom hem had actually been taken up and letting this down added a inch. We undid the bottom seam and this gave a very frayed edge but gave about another 3 inches.
My wife put bias binding over the edge adding another 1cm and protesting the fraying.
Adding about 41/2 inches to the bottom hem
then we repeated the adding the bias binding.
about 2 1/2inches longer.
Now all we have to do is get rid of some of the holes.
This will require some darning and patching to give the best possible finish.
Now this is finished all that is required is the movement of four buttons to give a slightly better fit and my some will have a "new cassock".
