Hi, have got this dress www.monsoon.co.uk/invt/93309286 which is very flattering and I have only worn it once. I am going out for dinner in a restaurant in London in a few weeks and want to look smartish but not too done up. Was thinking of wearing it with a long velvet coat I already own, but am not sure about my legs/feet - used to have good legs but sadly they are a bit on the chunky side now. Do I go for knee high boots with heels, or something like opaque tights and mary janes? Budget is limited! Thanks....
