MAGICMK Women Summer Casual Sleeveless Tank Tops Crew Neck Graphic Basic Black Shirts (S, Black+White)

Is the hem around the arm holes supposed to be finished (like the hem at the bottom of the shirt) or is it supposed to be more “rough” & look uneven?

Does this cover your butt and hips, or is it too short for that?

My shirt says 95 percent Cotten but the description says something different ???

Does the plain black version of this tank have a pocket on the front?
