Best way to manage bikini line (12 yo)?

[MrsFogi]

Dd has swimming in the morning and has announced (just before 10pm) that she wants to ensure no hair is sticking out of her swimsuit. No problem there but as she is swimming at 9am I have limited options available to assist with this operation - so are we best to go with shaving (wet shave with razor) or hair removal cream?
And going forward (i.e. I can go to the shops after swimming) what is best at this age?

As long as you know she doesn’t react to the cream I’d go with that as the regrowth from shaving is a nightmare of itching.

I don't know if it's any use as it's not about grooming but sports direct sell the slazenger boy short swimming costumes and for 8.99.

Dd loves them as they don't need pulling out your arse every five mins but they would eliminate the worry about bikini lines

I'd just trim short with scissors tbh
