I've just bought this www.johnlewis.com/weekend-maxmara-pirania-cotton-knit-pattern-jumper-ivory-multi/p5846247 jumper, second hand off Vinted.
The washing instructions say hand wash only... but it's 100% cotton and I'd much rather be able to bung it in the washing machine. Do you think it'll just shrink a bit (not a disaster, it's quite big) or will it be ruined?
