I need some new long sleeve tops for work and quite like the look of these from Cos. If it fit nicely and I'd probably buy a few colours. I've not bought from Cos before, does anyone have any insights on the general quality, sizing, durability etc?
I'm a bit worried it's ultra thin and won't be warm enough. it's hard to tell from the pics:
