I would really like 2-3 thin l/s vneck or round neck tops but can't find anything that's not mostly synthetic. There was mention of M&S ones last year but I can't find any on the website that look right. I have some lovely thin ones from Joules from last year but they're 70% viscose and I sweat like mad in them although they're 30% wool so great. I got some wool/silk ones this week from Charlotte & Co but they're a bit itchy tbh although lovely in every other way.
I don't think uniqlo would fit me as I'm an 18/20 up top and anyway they're not natural fibres but that kind of thing would be perfect as they're thin, stretchy and come in lots of colours!
