Once you’re used to it, most people wear theirs through the whole day. Start with a few hours a day for the first week and build up from there.
It should feel firm, but you should always be able to breathe deeply and move freely.
Take it off if anything feels uncomfortable. Having a spare to rotate keeps them fresh and holding their shape.

Measure around the fullest part of your chest and check it against the size guide on the product page.
If you’re between sizes, go for the larger one. Our garments fit snugly by design, so the larger size still gives firm compression and is far more comfortable all day.
Sizing down won’t make it work any better; it’ll just be uncomfortable.
