I bought the M&S high impacts instead of a Macom so totaly different bras but i think there the same material, deffo dry naturaly, mine shrunk just off drying on the radiator so i wouldn’t risk it xxx
@giraffequeen i think mine feels a little tighter after even drying it naturally too lol, the band feels kind of loose for me after wearing it over my strapping for the first week though but the cup area feels tighter xx
