Even with gentle usage and care, all bras will lose their shape over time as the elastic fibres in the band and straps begins to deteriorate. It's generally recommended that a bra should last anywhere between 6-9 months, although we think that with good care your bras should last a lot longer.
If you show your bra the love and care that it deserves and you leave a bit of time between wears (so the elastic can bounce back into shape) then a quality bra should last you between 9-12 months.
You should wash your bra after 2 or 3 wears, or once every 1 or 2 weeks if you're not wearing it every day. Wash your jeans as rarely as possible, unless you're going for the distressed look. Wash sweaters as often as needed, but be careful not to stretch or shrink them as they dry.

To sum it up: you should wash after one use if you're sweating really hard. However, if you're living a low-activity quarantine life, give yourself a good three wears before you need to switch.
There's nothing wrong with wearing a bra while you sleep if that's what you're comfortable with. Sleeping in a bra will not make a girl's breasts perkier or prevent them from getting saggy. And it will not stop breasts from growing or cause breast cancer.
