These are gorgeous.  I am 5'9", 125lb, not super leggy, got size M and believe this was correct.  They came up to about the same place on me as they do on the model and were, barely, narrow enough to fit nice and close.  I think that I am just not a 15 denier girl, though.  They did get runs the second time I wore them, I was careful with washing and putting them on, but they were just too delicate for actual wear, and the price precludes buying them in quantity.  Had they reinforced heels as well as toes, I think they would have survived longer.
