How can i scale 1 side of the mesh? I try make a model of a bottle, i started the shape from a bezier circle, though the bottle got a rounded, squared look. Extruded it up to the top of the bottle. The problem is that this bottle is not symmetric on both sides so i need in some way to scale only 1 side of the bottle, i just dont know howto. I include a photo of my blender. Would be very glad if some one could tell how to do this. I am new to blender, so this might not be best way to start with a bezier circle? Also glad for advices.
Place the 3D cursor on one of the vertex on the opposite side of the mesh, press . to transform around the 3D cursor, and optionally press O to turn on Proportional Edit mode.

Select one of the top or two top edge loops (as prefered) and scale them with S
