ok so I am getting EP:FC in exactly one week and I was wandering if I could do character customization on a third party website so while I'm off my main computer (I have a chromebook and windows) I can still look at the customizer

does anyone know a website to deal with this?

Idrk what u mean by char customization on a 3rd party website. The character can be edited in game with the set shirts and hair, just like in EP. I don't remember if u can import ur own clothes there like u could in EP, but if yes, then thats your seemingly best shot.
