How should i get my hair done?

k my hair right now is a light brown about collar bone length, a bit longer, with layering up to about my cheekbone. i have sideswept bangs that are just longer than my eyebrows. (they're just a bit too long) i wanna get something different... but i want some things to be the same. i want my bangs to stay, just maybe shorter. my friend also suggested getting more straightforward bangs. i want my hair to be a darker brown. (i swim and the chlorine has been making my hair lighter cuz i dyed it just a big darker than my natural color) and the last thing is i want it to be long enough to put into a ponytail. (it's okay if i have to bobbypin some hair up.) any suggestions are welcome!! THANKS!!!
