tbf, its just a style.
you can always let your hair grow back out, redye it (although growing it out might be better, i wouldnt advise you to over dye/kill your hair
)
you can always donate the clothes away that you feel dont suit you anymore
you can always wash the makeup off
ive personally been sitting with my decision for months (possibly a year or 2, i havent been keeping track)
its ok to sit with it and think about it for a bit
but also in this case, i dont think it can do a horrible amount of damage so trying it out isnt a horrible idea either
whatever feels best for you.
whatever makes you happy
even if it takes you a couple of tries to find it
