IMO one of the biggest issues regarding short/long is if your hair is straight or has wave to it. If you like Nicole’s look but have wavy hair you’ll be spending a lot of time taming it. I’d love to have a bob, but my hair is has a slight wave to it that isn’t particularly noticeable when it’s long. But when it’s shorter, instant mushroom head
And I’m just not willing to put that much time into it.
