How do I hide a crop top??

Basicalllyyyyyyyyyyyyyyyy.....

I love this crop top and I wanna wear it to a theme park on Saturday coz our school is taking us. So I wanna wear this crop top that my mum hates but I love. Should I wear a jumper over it or is there another thing I can do?

Update:

Okay so I wore a jumper over ontop...however whilst my mum was on ft with my dad she said let’s see what’s under it but luckily my dad interrupted so then I pegged it upstairs and put my spare shirt on underneath😅
