I am chunky of calf and tried [[http://www.amazon.co.uk/gp/product/B001AE93FI/ref=ox_sc_act_title_1?ie=UTF8&m=A3P5ROKL5A1OLE these]] on the other day and they fitted rather nicely - I'll be wearing them mostly with dresses for work but really don't know whether to go for a nice safe dark brown or go for black patent? What would you go for?
