Don't go crazy--I find a mid calf black (or other neutral color) skirt to be the most important item I pack. I bring a variety of tops, lightweight jackets, and sparkly (ie, fashion jewels, not the good stuff) jewelry and I am ready for just about anything. Since I am notorious for spilling a little tea/lunch/etc. right on my chest, I pack tank tops--which I can easily switch out under a jacket or shrug and have a "new" outfit. I usually buy them in colors or patterns to brighten up a black ensemble. For my last 14 day cruise, I packed 2 long evening gowns (wore each one twice for formal themed nights), 2 cocktail dresses (wore each one twice for formal nights), mid calf skirt, black silk trousers, and the tops to mix and match. Wore everything at least twice and had plenty to choose from for each night at dinner. During the day, my go to are yoga pants and cotton tunic tops....easy to roll up and pack. Had one medium size suitcase (checked, less than 50 lbs) and a carry on. Just a tip for evening dresses--lace doesn't wrinkle, so just roll it up and shake it out!! Have fun.
