Hair advice needed! 💇🏽

Dani
Hi everyone, I'm really wanting to get a hair change this week (guy and best friend problems😒...need a pick me up and I want to look amazing! I can't decide whether to get a chop/what length...my hair is a few cms above my butt atm. Or just get a healthy trim and do a colour. I'm loving purple and also grey/silvery tones lately. But also don't mind going chocolate/mahogany Browns either. I've attached some photos..please vote or any advice is appreciated!! xx 
* the last photo is a colour I adore, but I don't think I could pull it off 😕
