Any tips appreciated!

New to Poshmark & I really want to learn how to gain more followers. Are there any tips or tricks to do so? I haven't made a sale yet but I still have more stuff to post. How do you trade? Hopefully I can get the hang of this to be able to bring in a little extra income. I'm a full time single mom and student working on a bachelors in legal studies. If you have any professional business attire or tips on how to dress in the legal office setting would also be great! Thank you fellow Poshers!
