I tend to agree with you Rae - if it were just a straight chopping off of the hem, it would be inexpensive, But taking off a couple of inches and reattaching the band is costlier, plus looking at where the pockets are placed - I think they would look in the wrong spot on a shorter jacket. I'll check out my thrift stores and see what's around.
But it's good to know the ones I have are too long for skirts/dresses - I always kind of wondered and now I have confirmation!
