As a first rule, as you move up the ear, choose to stack your selection of earrings from largest to smallest, starting with a drop earring and working upwards to a close-fitting huggie or simple stud for a considered waterfall silhouette.
For a more minimalist look, stack similar earring designs, such as hoops, where proportions can be the subtle differentiator to achieve a less uniform look. Consider pairing inflated huggie hoops which offers volume and graduate down to a classic large hoop at the lobe in a finer width, all within one precious metal for a cohesive finish.
An alternative is to work from statement pieces up to less intricate designs for a maximalist look; avoid pairing similar-sized pieces but instead experiment with texture to create impact as you descend down the ear, consider a centrepiece of Pavé hoop or a shoulder-grazing long drop to achieve a high octane impact and play with mixed metal styling in increasing visibility of your stacked pieces.
