Hi Stylefan --
Agree with all that the dress looks stunning on you. And given all the context you've given it doesn't seem to be an issue to repeat unless Mr SF voices some much stronger opinions about the dress standing out "too much" vs just standing out because you look wonderful in it!
Re shoes: they're such a try-before-buy thing I have a hard time recommending anything. Clarks tend to be my go-to comfort line because of my particular issues, not sure how they work for you. Are any of the above from Taryn Rose's line (she's an ortho or podiatrist, can't recall)? Spendy but since you aren't buying a new dress....
Good luck on the shoe hunt!
