Platinum blonde to natural ombré?

[L00pie]

Hello just wondering if I can pick people's brains again? My client is grey white all over I normal bleach her roots the goldwell 10v to tone all over! But she's now wanting to go like perrie from little mix colour just wondering what colour and technique I should use? As don't want that horrible line that home dip dyed get... I'll attach a few pictures of what she has sent me! But she said she may want it slightly light on ends but I only confident in goldwell and Paul Mitchell colours thankyou if anyone could help me!!

I would first tone all of the blonde to a warm/ golden/ beige tone, then I'd do a root stretch using a Demi as it will grab and hold better over the blonde.
You didn't say what her natural level is ?
