It may strike you as elementary, but you’d be surprised at how many women fall into this trap, dressed to the nines, stuck in some feed hall flanked by casually dressed diners (and, all too often, their screaming toddlers). Very nicely ask, ”What type of place are you thinking about?” If the place sounds unfamiliar, ask him about the dress code. (Better yet, see if the restaurant has a website, where you can get a feel for the atmosphere.) Dress to look and feel your confident best.
