It looks like a gift. It's a technique — five centuries old.
It has a name
Sprezzatura — from a 1528 Italian court manual. 'Studied carelessness': effort made to look effortless.
The ten-second move
Once the outfit is 'done', undo one thing on purpose — push a sleeve, skip the top button, half-tuck the hem.
The flaw is the finish
Perfection invites inspection. One relaxed note says there's nothing to inspect — this is just how she looks.
Stop at one
One deliberate undoing, not five. Past that it isn't ease — it's unkempt.
Try it
The most forgiving place to practice is a good shirt.
