It's not every day we spot an item that can be dressed up, dressed down, worn to work, and worn out on the town. But when Princess Mary [1] stepped out in a white lacy skirt, which she paired with a silky shirt of the same color, we knew we'd found "the one," aka the most versatile piece to add to our Summer wardrobe.

While Mary perfectly demonstrated how to rock it at a big event — in her case, 2016's Copenhagen Fashion Summit [2] — we can easily picture it styled with a graphic tee and sneakers, a blue button-down and flats, and so, so much more.

Take a look at Mary's must-have fashion item ahead. Then, pick one up for yourself before the Summer season really kicks off.

While she went a somewhat formal route, we can totally picture this piece styled a variety of ways — even with sneakers!
