Would you consider wearing a hat for your friend's wedding? A fascinator type of thing which draws people's eyes to your head and makes you look a little taller?
I am just under 5 foot and, sadly, not a size 10. I was always told not to wear shoes with ankle straps or mary jane type shoes as they shorten your length. Wear clothes with detaling around the neck and shoulders rather than the hem of your skirt/dress as again the eye can be drawn to your upper half rather than the length of your legs.
One good thing (if you are single) is that the slighly smaller man will be attracted to you. My DH is 5ft 6 and DS1 and DS2 are both taller than him. I never had to refuse going out with a man because I was too tall for him, unlike some friends!
If anyone says anything rude to you just reply, with a superior and knowing smile, "haven't you heard, good things come in small packages".
