As someone who's certainly old enough to be a granny and a MIL, wouldn't be seen dead in Per Una - it looks awful in our local shop and, in 99.9% of cases, is awful. I agree with whoever said it has completely lost its way. Who is it for??? Yes, there are a very few OK plain items lurking among the dross, but I really don't want to look.
Also agree that Portfolio a complete waste of space - is that for people older or younger than Per Una, or what ?? Sure I read it was to be phased out - good thinking, if so.
As for Classic Collection being for MILs, you lot must have some very old MILs - though can't imagine buying it however old I become.
Altogether, much of their womenswear is naff. Only label I take trouble to check through in bigger stores, such as Marble Arch, is Autograph. Not all wonderful, but have got some good everyday stuff from them.
