So I rarely shop eg at high street stores and was only as I was in London the other week for the day, passed Stradavarius as I was sweating like a pig in my shirt (cotton) and grabbed a burgundy t shirt there. So I returned the other size (I got 2) and came away pleasantly surprised with this and a top. The quality is great, super soft and it goes with a bright Oliver Bonas skirt I got this summer:-

So anyway, give them a go!
