Agree with what has been suggested by pbd & mt. spokane.
The shot seems to have been taken with white fluorescent light coming from the left casting deep shadows in the already dark clothing. It appears more of an issue with the lighting than the camera.
A few more points -
What camera were you shooting with. I have this weird problem with my 5D3 and the 6D which "seem" to underexpose by 1/2 or 2/3 of a stop. Maybe you are experiencing a similar phenomenon. I usually compensate this by ETTR and bringing down the highlights in post.
1DX, 5D3, 600D, RX100
16-35L, 24-70L II, 70-200L II, 100-400L II, 50L, 85L II, 135L, 17TSE, 24TSE, 40, 100 macro, 18-55 II, 55-250 II, 1.4x III, 2x III, 600RT x 4
When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
