Hair Debate: HELP!

So the debate is underway...do I cut my hair or let it keep growing? I have pictures below of my shorter hair and the length it is now! I have a hair appointment on the 19th. Whether I cut it or not is a possibility but I will definitely be coloring it. Here are some of my color options:

Reasons I love long hair--it's beautiful and reminds me of a mermaid and can be really fun to style. Now that I've mastered straight and different types of curling, long hair would be really fun to do!

Reasons I love short hair-- sassy, fun, easy to do and many people told me I looked older with it.

Don't mind my snapchat caption lol 

Okay vote below with the color option you like best and if I should go short again or keep growing my hair out! I want to know your thoughts!! Happy Friday, peeps!
