Thanks, ladies, that's really nice.
I assume that we all have a cost per wear / purchase price pain point, then? If something costs less than £X, you have different expectations re longevity etc, whereas for others, that cost needs to be less than £Y.
Re viscose tops, I've had some that are really good (seems to be the knitted, thick, fitted viscose), and others that turn into rags (seems to be the thinner woven viscose that does this). I have a woven viscose blouse, though, that still looks fine but is also going thin and probably won't last beyond this summer. It was £25, so I won't cry for it, but I think, now, I would rather pay a little more if it means it lasts longer and looks good for the whole of its life.
