My suggestion is to go for the trim first. You can always ask her to go shorter next time. Always can go back to get it shorter, never can go back to get it longer heh.
Also, some people's version of a "trim" or "just tidy it up" could end up being BSL. So just have her tidy it up and see what she's like. Take the relationship easy at first
And I took a look at your pics, and OMG I LOVE THE CURLY BRAIDS!!!!!!!!!!!! You are so freaking adorable!
