Based on the visible evidence in the image:

1. **Eyes**: Her eyes have a slightly downward gaze, which can indicate contemplation or introspection. The eyes do not appear to be wide open, which might suggest she is not particularly surprised or alarmed. Instead, they have a more focused or intense look, which can be associated with concentration or strong feelings.

2. **Eyebrows**: The eyebrows are slightly pulled together, which can indicate confusion, concentration, or mild concern.

3. **Mouth**: Her lips are pursed and tightly closed, which can suggest a myriad of emotions such as tension, displeasure, or determination.

4. **Posture**: She's seated in a relatively rigid manner. Her posture doesn’t convey relaxation. Instead, it suggests she’s in a formal or serious setting, or she is trying to present herself in a poised manner.

5. **Hands**: Holding onto her glass can be a self-soothing gesture, something people often do when they are feeling tense or nervous. The fact that she isn’t drinking and is just holding the glass might suggest contemplation.

6. **Facial Tension**: There seems to be a slight tension in her facial muscles, especially around her jaw. Tension can be a sign of suppressed emotions or underlying stress.

7. **Dress and Environment**: She's dressed in an elegant manner and is surrounded by a luxurious environment. This doesn't directly indicate an emotion, but it places her in a context that might be formal or significant.

8. **Authenticity of Displayed Emotion**: While she exhibits signs of tension and contemplation, her composed posture and setting might suggest she's attempting to maintain a facade of calm or elegance, despite possibly feeling otherwise.

In conclusion, the woman appears to be in a state of contemplation or mild concern, possibly trying to maintain a composed or dignified exterior despite some underlying tension or unease. Her body language and facial expressions suggest a mix of concentration, tension, and formality.
