For the neatest look, make sure your dress doesn’t drag the floor (looks sloppy) but merely skims your heel.
Even if you think your feet won’t show under a maxi, remember that when you sit or walk, the shoes will definitely show. Embellished sandals add a fun, summery vibe to the look.
If you need the height of a heel, try a wedge sandal. It is substantial enough to keep the look more casual (where a stiletto is too dressy), but it gives your height a boost.
