Portfolio was, I think, supposed to be the 45-60 range - for those women too old for Limited Collection & Per Una's cutting-edge, fashion-forward stylings, yet too young for Classic Collection's World of Elastication. The launch collection was actually fab - great wrap dresses, flattering trousers, decent quality fabrics and attractive prints. I bought quite a few pieces, despite being about 35 at the time. Portfolio lingerie was good too.
And then, like all great M&S ranges, whoever they'd paid a fortune to launch it moved on, and it went very meh, and then was quietly dropped. I might be remembering it with rose-tinted specs, but if they'd managed to keep Portfolio going, I'd still be spending a fair bit of my wardrobe money there twice a year.
