Keep it casual, but don’t think that means you have to make it boring. You can go sophisticated, classic, and sleek with a fitted tee in a neutral color, some flats or sneakers, and a small purse, or you can dress it up just a bit with a button-up, flowy top (tucked in), blazer, or sweater. If you choose to go the sweater route, you can go with something fitted, cropped, or a even a little slouchy as long as it’s tucked in in front (check this one out: https://www.instagram.com/p/CMaphemp3Y7/ ). As long as your top has some shape and isn’t too fancy, it’s probably safe to pair it with your cargo skirt. The same thing goes for shoes. Go no fancier than a simple pair of pumps (and go as casual as a pair of flip-flops), and you’re good.
