So...I'm going to a friend's birthday meal at a posh restaurant on Saturday, but haven't really given any thought to what to wear until now! I've got a dress a bit like the one in this photo, except with long sleeves. I'd like to wear it with black opaque tights rather than bare legs - but have no clue what boots or shoes would go well with it. I'd need to be able to order online and I can't afford to spend more than around £50-60 max. Any ideas?!?
