This is still super formal, so either wear the same attire you would to a black tie affair or wear the fanciest cocktail dress you can find. If you go the cocktail dress route, make sure there are rich details like beading on the frock and that you are strutting your stuff in your favorite stilettos.

If you're getting invited to something that says semi-formal, it's either your sorority's annual event, prom, or you're attending a family member's sweet 16. Similar to black tie optional, but more forgiving, you can go long or short or opt for color-coordinated separates a la a full midi skirt and matching top.

This is where tailoring is key. Try a formfitting sheath in a basic hue and always pair with a leg-lengthening pump (for extra inspiration, Google Claire Underwood's work attire in House of Cards). *You'll probably find this dress code on invitations for rehearsal dinners or showers.

Pick a flowy, long dress (remember that it may be windy, so a maxi is perfect!). We never thought we would say this, but leave your heels at home and opt for embellished flat sandals with a pretty pedi to match.
