Just read the other black tights thread and noticed a lot of hate for black sheer tights. I wear them pretty much every day to work with a grey/black suit. Opaques aren't formal enough and look odd with a suit anyway. Fishnets etc a definite no for work. I do wear nude tights in the summer, but in winter and autumn tend to go for sheer black tights.
So, what is the alternative, because I can't see one!
