I have some great M&S cotton opaques but they are only available in grey (well, and black but I don't wear black). Where else is good for other colours, I need navy, burgandy etc? I want plain or perhaps with a cable in. M&S Large are perfect, generally one size tights I find are too small. Are White Stuff any good? Are Boden any good (££)? Need to be able to buy online.
