Correct wrinkles in mesh

Hi

Total blender noob here. I am working on a cloth materials (inner wear). How do i smoothen / curve this face. It seems to have some sort of wrinkles. I tried deleting the face and face fill but still the wrinkles keep coming back. Please help.


Thanks in advance.

Cheers

An image of the wire frame would help, but I am quite sure it is filled with triangles now. Try to fill it with quads instead.

Use a polysphere topology instead of a multi pole.
