We're going to a work black-ish tie event this week (ie most men wear black tie, and the women dresses of varying lengths). I have a very old 'little black dress' - v classic velvet, sleeveless - which is several inches above the knee. Can I wear it with knee high boots? The boots in question have a high, but not stiletto heel (they're Hobbs 'Boyd' boots). The venue is a marquee and apparently quite cold, so boots seem to make sense. I'm told I have the legs to carry off the dress, but at slightly over 40, I don't want to look like mutton, nor like I've walked out of the nearby S&M parlour. Please may I have your thoughts? Many thanks!
