It's pretty at this length. It's also a giant pain at this length, & hot, & heavy. If you don't mind the headaches & heat, keep it, but don't go below your butt - as you cross over to weird at that point.
it's like any other hairstyle: as long as it matches your frame and it looks good with your face shape, it's ok. it has its advantages (the variety of hairstyles) and disadvantages (hard to wash, to maintain healthy). i do prefer super long hair on myself
