I certainly have! I no longer wear waterfall cardigans (and find I am judging those who do), or linen trousers, sensible shoes (especially from Clarks) or sarongs.
I no longer even LOOK in Per Una, except maybe a pitying sideways glance, or in Wallis, for fear of dayglo polyester.
I have taken to wearing tapered chinos with snappy blazers, jersey dresses and leggings with summer dresses- although I think the jury is still out on that one.
