they have got some great ones in H&M.
Nice muted mauve, grey, teal marl type colours, really soft knit, like a long sleeved t shirt but soft like a thin sweater.
They are LONG! Which I need as short ones are just wrong on me.
£7.99 and I was handed a 20% off card today when I went in. I think I will go and get a couple more tomorrow, they fit so nicely.
