Professional hairstyles?!

[ManAliveThisThingsFantastic]

I am currently sporting green and black hair which I love but don't think is very professional. I have just received a job offer and will be meeting with "big" clients and prospective candidates.
I am seeing a hairdresser to get an all-over natural colour but unsure of a cut.
I will have dark brown hair, it is currently past bra length. I am quite small and skinny and don't want to lose too much length as I have a big nose
Any advice/pictures appreciated!

Do you actually want to change it? I mean, did they offer you the job knowing you'd be meeting with clients and having seen your hair?

I do want to change it, yes. I feel like I've outgrown my hair now.

Ah, okay. I just ask because I changed my (pink at the time) hair once for something against my will and it was a shame! What's your hair like in terms of thickness, waviness, etc.?

[ManAliveThisThingsFantastic]

It is quite thick and has a wave to it. I do tend to straighten it though.

I just googled this and all the women have natural coloured hair - thought it might ell be died that colour, and otherwise it's just well groomed without any sticky up or shaved bits. So I think you can do what you like with a good cut.
